As for Apple, it's a shame they don't ship 32gb laptops with touch screens.
I'm currently on an ageing OG X1 Carbon (i7/8/256), which has a sensational keyboard and track pointer, with a superb light and strong chassis; for my next, I'm hoping they'll upgrade the core count to 4+ and memory to 32, and an AMOLED display.
I use it a lot for document reviews, working with spreadsheets, and anywhere that touch corresponds more with manipulation of the object on screen.
I completely disregard it when the laptop is docked though. For me, mouse/kb habits take over.
And since I'm often working in Kenya it can be quite difficult to get service for Apple, having parts I can switch out with a screwdriver is a huge blessing. And it's stupidly tough, I've fallen directly on it and it's survived in the past.
There are some things that I think could be better. I think Windows is a bit ugly, hardware does not feel polished like in Apple but it's not nowhere as bad as Dells used to be. The only thing I go back to Mac when I need to do iOS stuff and sometimes when i get something from designers in Sketch format but it is unlikely that I will return to MBP anytime soon.
I find myself touching the screen when reading, on actionable wizards etc. So, it is mostly usability bonus for stuff that I could do in mouse. Funny thing is that I really didn't notice first that I started to touch screen.
Apple refuses to open up their dev space, like the worst kind of community citizen, and your response is to support that behaviour?
And my Mac runs for weeks, sometimes > 2 months, without a reboot. I've had to reboot the XPS on average twice a week (due to crashes, or updates, or really weird performance drops).
No thanks..
The build quality is top of the line, the drivers are solid, and everything just works. The trackpad is industry leading, and the keyboard is great too. Performance is exceptional, especially in the 15" which comes with a HQ processor (not ultrabook-grade) and a discrete graphics card. It has a PCI-e SSD. The price is reasonable compared to the competition.
But despite being IMO the best laptop available, the main reason I choose them is because every so often I need to boot into OSX for testing, or to do something Mac-only. And nothing else can do that.
