I left my old job recently. And consequently found myself in the market for a new laptop. I hadn’t bothered replacing my old Acer Aspire V3-571 with custom 1TB Samsung SSD that had failed within two years. Because the Toshiba Satellite Pro P50-C-12Z my old job supplied worked fine as both a home and work machine. Especially once I upgraded it with the SSD from my home laptop. However, once I left that job, I found myself relying on a 10-year-old Dell Inspiron for a couple of weeks:
That Inspiron is a loyal old work horse that has served me well as both a dev laptop and file server for a decade. And has been my go-to machine whenever other, newer, higher-spec machines have failed. It's had its screen and hinges replaced. And has had its hard drive upgraded several times with various SSDs. So saying it has lasted 10 years is a wee bit Ship of Theseus-y. But the motherboard, fans, etc have all stood the test of time. However, it just isn’t fast enough any more for modern development, so I needed a new machine.
After some research, I ended up opting for the Dell XPS
13. With 16GB RAM, 512GB PCIe SSD hard drive and the new 8th generation Kaby
Lake Processor (i7-8550U.) I initially ordered the previous model. Which was
identical in all respects to the above spec except the processor (it was an
i7-7550U), and the price tag: the old spec was £300 cheaper. However, after reading several reviews that all suggested the improvement in performance with the 8th gen processor is significant, I cancelled and ordered the new spec. It cost £1649 in early
November 2017. At this time, in late November 2017, it is now retailing at
£1547 on Amazon. That’s quite a price change in only a few weeks. Not waiting a
few weeks to see how the price settled is my only regret so far about buying
this machine.
The main thing that makes the 8th generation
processor so much better is that it has a Quad Core, compared to the
previous generation’s dual core. So, even with a lower clock speed, the newer
processor burns through tasks like building Visual Studio solutions about 60%
faster than its predecessor. That’s pretty significant. Performance gains are
usually on the order of 10-20% increases between adjacent versions. As the
newer processors have a lower speed, they also run cooler. So, except when you’re
building solutions, you almost never hear the fan kick in. I've found that browsing the
internet, watching videos, and even using MS Office are all silent experiences
on this machine.
I had heard that coil whine (a low pitched noise that accompanies
processor-intensive tasks like watching videos) was a problem in the previous
model. But I haven’t experienced that problem myself in the three weeks I’ve been using my new machine. Similarly, I had read reports of the wireless network card
being unreliable; but my machine has performed perfectly. It hasn't dropped connection to my home wireless even once.
The main things that drew me to this model were the form
factor. (A 13.3 inch screen in a machined aluminium chassis, that would usually
only be large enough to hold a 11 inch screen in other models.) And the battery life. (Dell reports
16 hours; I’m finding more like 9 or 10. But I do have the QHD screen,
which is more battery-intensive.) Every time I’ve bought a laptop before, I’ve
gone for power over convenience. But to be honest, the sort of 15-inch laptops
I’ve opted for in the past aren’t great for commuting (small tables on trains.) And they typically don’t have a good battery life.
(I’d have been lucky to get an hour or so on battery on my old Satellite Pro.) By comparison, this
machine runs and runs. If I take it to bed at night, I have to be careful not
to surf (do people still say "surf"?) or work too long. Because that battery could easily see me through til
dawn. As it is, if I browse the internet or watch a video for 3 hours or so at night on battery, I find I
still have 70% battery the next morning. That, to me, is better than having a
10% faster machine that doesn’t last as long.)
As a development machine
Honestly, I’ve not used this laptop heavily as a development
machine yet. Though I have experimented with running old Visual Studio
solutions on it. A solution with 36 projects Builds in 1-2 seconds in Visual
Studio 2015 Professional and VS2017 Community from a cold start. And Re-builds in about 15 seconds. That's amazing - better than any laptop or desktop I've ever had, full size or not, with or without SSD. On my old full-size Satellite Pro laptop with 1TB Samsung
SSD, that Rebuild would have taken about 20 seconds. I should warn that there are some gotchas in VS2017. e.g., if you leave the Lightweight Solution Load option on (as it is by default), then the initial build time for that same project is about 40 seconds in VS2017
Community. Also, the solution sometimes doesn't build at all. So, my advice is to switch Lightweight Solution Load off completely. It's not stable enough at the current time to be of any use.
I’m always dubious about using versions of Visual Studio in the same
year as they are named for. But VS2017 appears to be particularly bad in terms
of buggy-ness and generally poor design decisions. (e.g., I found that the Javascript Language Service (the part that should make Intellisense work for Typescipt and JS files) has been arbitrarily turned off in VS2017 for some of my existing solutions. Seemingly because some Microsoft developer had put it in the “too hard” pile to make Javascript / Typescript work properly in VS2017.) Note to Microsoft developers: if you can’t handle more
than 20MB of Javascript / Typescript files for a single solution, you’re just
wasting developers’ time. Don’t bother doing less than that and considering the
job done. Turning off features that worked perfectly well in previous versions
of VS is pretty inexcusable. The only reason for using Typescript over
Javascript is that it provides object-oriented capabilities. But you can only
leverage those features meaningfully if you have Intellisense. Disabling such a
key feature at such a stupidly-low threshold is like having a car whose doors
fall off if you go over 30 MPH. And closing bugs about same on the basis that you meant to do something that stupid is even more stupid than the design decision was in the first place. FWIW, I fixed the problems with JS/Typescript Intellisense that are evident in VS2017 by disabling the new Language Service completely using this option:
and including the following settings in a file named "tsconfig.json" in the root of my web project:

Anyway, this review is about my XPS 13, not the poor
design decisions of the Visual Studio 2017 development team. I mention these issues
with VS2017 vs VS2015 purely to note how hard it is to assess new hardware if
running new software too. Sometimes, it’s not the hardware that's to blame for any failings
observed. Overall, like-for-like, my XPS 13 performs better than my old
Satellite Pro + SATA 3 Samsung SSD. Even though that machine was no slouch. I’m glad I bought
it, and will continue to use it as my main development laptop.
Battery Life
In terms of battery life, the XPS 13 is a world away from
any laptop I’ve owned before. Realistically, I get about 10 hours out of it if
I’m just browsing the internet, or watching videos. As noted, I haven’t used it for
actual development in anger yet. But going by the way the fan kicks when I build VS solutions, I’d
suspect that I’d get around 4-5 hours max out of it at full throttle, possibly less. All previous laptops I’ve used have
only got around 1-1.5 hours on battery, even if I were only browsing. So, whilst I have to be
careful this doesn’t make me sit up too long at night. It is a huge
improvement. That battery life is the main reason I bought the XPS 13 over its big brother,
the XPS 15. Every time I’ve bought a laptop in the past 10 years, my ‘sensible’
head has kicked in and coaxed me to go for raw power over portability and
battery life. With this machine, I don’t need to compromise. It provides both ultra-portability, and processing power in one package.
Whilst no doubt the latest generation XPS 15 probably could out-perform this model in sheer processing time. You can’t argue with sub-5 second builds in VS2015, combined with a full
day’s battery life for commuting or using in the evening for lighter tasks.
Other features
Other features
The XPS 13 has two features that I particularly like. Firstly, it has a nice, carbon fibre, rubberised keyboard surface. The keys themselves are pretty tactile, chicklet-style. As a touch typist, I find it suits me very well. But the palm rest is rubberised, which makes the keyboard pleasant to use if the laptop is cold. Had Dell opted for Aluminium all round, I think that would have made for some pretty cold hands when typing a quick email first thing in the morning. Or when transferring the laptop from a cold car boot to a warm office.
Secondly, the keyboard is well-lit. With differing levels of white lighting available. Including "off." In a dark room, that backlighting makes positioning your hands far easier. Also, the keyboard light only comes on when you type; so it's not distracting if you generally want a keyboard light, but also don't want to be distracted by same when watching a video.
Minor Quibbles
My old Inspiron and new XPS 13 both have one design feature that I find annoying. Namely, there is a battery charging light right on the front of the machine. And it can't be disabled. It goes off when the battery is fully charged, but it'd have been nice to be able to switch it off electively. My old Inspiron battery has reached a stage where it doesn't hold a charge any more; it's therefore even more annoying, as it flashes orange to warn that the battery needs replaced. My new XPS 13 is too new to be able to tell if it does the same thing, though my understanding is that it will when the battery is too old to charge any more. It'd be nice not to have to use black electrical tape to switch this feature "off."
Secondly, the webcam is badly-placed. I don't use it anyway, so it's not an issue for me. But if you do a lot of web conferencing, be aware that it is placed on the bottom-left of the screen. This is because the 13.3 inch display takes up nearly all of the height and width available. But it means that any Webex you have will involve participants looking right up your nose. Not pleasant.
Lastly, the hinge on the lid is very strong. I personally like this, as it means the screen doesn't move when you use the touchscreen. But some people have complained about having to use a whole two hands instead of one to open the lid. The main issue I do have with the lid is that it doubles as a very effective set of pliers if you placed your fingers on the hinge whilst opening. (Just as well you need both hands to open it then really, isn't it?)
Other options
Other options I considered included the Razer Blade Stealth.
(In the end, I decided the lack of a 8th gen processor, combined
with the fact I could only get the “gamer” version with a green logo and
rainbow-coloured keyboard lighting were deal breakers for me. Plus, support
is US-based whilst I’m in the UK.) I also liked the HP Spectre very much indeed – it seems a very
nice machine. Just not quite as capable as the XPS 13 in terms of power or
battery life. Beautiful, though.
