Received mine yesterday. No keyboard -- just wanted the tablet function.
First thing out of the box, plugged in and entered my Google info. Started to download Android 7.0 update -- a bit over 1 GB. After download and verify completed, notice that "Not enough battery to install update." Had to let charge build up to about 35% or more. Went away to eat dinner and returned to find all updated and ready to proceed.
Coming from Samsung Note 10.1 (original version). Transfer was easy: opened Google app on the old tablet, followed the prompts, and all apps, data, and "most" settings were transferred. I had to add my frequently used apps to the home page. No issues with setting up apps -- most required initial login on first opening.
Great performance so far. NO issues with any lag. Apps open super fast. Very much liking this.
My phone is Note5, international version -- that means it is still on Android 5.1, not Marshmallow, so really happy with updated Android. Teh original Note 10.1 would not update beyond Android 4, so it tended to bag down really bad on apps looking for an updated OS.
Also installed the Microsoft Office apps from Play Store and was able to sync spreadsheets from the Microsoft cloud between my PC and the Pixel C.
Overall, VERY pleased.
