Best Buy sneaking in a recruitment ad in the response header when their servers were sucking ass.

Me at BestBuy today: Oh man, you got the got the Pixel 2 XL? This is looks good and feels good in hand. Last time I stopped by, the other guy had just the Pixel 2. Blah blah blah.. so is this running the 8.1 or 8.0?

Verizon associate at BestBuy: The 8.1

Me: oohh, you got that preview huh? *goes into system to check.. dude it's running 8.0

Verizon associate: oh really? Dang, I forgot. I'll side-load the APK.

Me: 😕😒😂 I hear you.
*At that point I lost hope in humanity*

!rant Need advice. Been wanting to switch to Mac-based dev for a while and finally found an $810 new-in-box iMac 21.5" 4K with retina / 3.1Ghz quad / 8GB / 1TB bought new from BestBuy late 2016 but manufactured sometime in 2015. Never opened. Any potential pitfalls with that and expected OS updates or dev tools?

Hello Devs, Please Suggest Me A Good Laptop.
Specs I Probably Need:
256 or 512 SSD
i7 6th gen
8 or 16 GB DDR4 RAM
Dedicated Graphics or Touch Screen(Ultrabook or something)
Really Confused between Yoga 910 and Lenovo Y700. Or what will be the best device(Portable and Powerful) for us?
