MacBook Pro 15" & Chromebook user here
I thought I would provide some 100% impartial comments. (I buy what works for me.) I own a 1TB SSD 2013 MacBook Pro 15" Retina, and tried two Chromebooks, as travel machines. Don't knock them. Google have put a LOT of thought into the keyboard, something you don't realise until until you look at it. Operating a browser through tactile keys makes the whole web and cloud apps (Google docs in particular) experience a lot more pleasurable, fast and intuitive than using a regular laptop. I ONLY use my MacBook because (for now), I cannot escape Adobe CC, using Illustrator almost every day.
Plus, the touch screens on my Chromebooks (I tried an Acer then a Lenovo) made them even nicer to use, swipe to browse, pinch to zoom, all natural after using tablets and phones for so many years. I sold the Chromebooks because one was too slow (the Lenovo) and the left shift key on the Acer was horrible (a flaw in ALL Acer laptops, Windows included!) However, this Pixel looks like the perfect machine if you do NOT need the Adobe suite, Garageband or any other power user app.
If I can find a cloud based vector drawing app that does what I do in Illustrator, I'm dumping the MacBook. I run my business on Google docs, and it's oustanding (light years ahead of iCloud in many ways), and Google's invisible AI is everywhere. Did you know that if you store a photo of (say) a road sign on Google Drive/+/Picasa etc, when you do a search on a keyword, it will find text in the photo? IE, if you took a photo of a sign that said 'London M4' and searched for 'London', the photo (and any other content, text etc) would appear in the results?
Don't knock Chrome/Google, they are getting there and the Pixel 2 has the power to last until more poweruser cloud apps arrive.
I'm very very tempted. And the use of twin USB-C ports was a smart move too, as was the SD-Card slot. The new MacBook reminds me of the first Air, that whilst an engineering marvel, was knobbled by lacking ports. I waited for the next generation and still consider the Air 13" the best laptop in the world. But I love a touch screen, so won't be getting the MacBook or another Air until Apple make that brave step and introduce pinch to zoom and swiping on the screen to OS X.
