I liked a lot of things about iOS. Apps for Android tablets are still largely terrible and there is some bizarre behavior around SPens and multi-touch that I don't understand. But I could never go back.
The biggest benefit is I have all my files automatically synced between my phone, tablet and laptop. I never have to manually push something to the right app, then figure out how to get that on my Windows laptop. It's just there. Whether it's emulator save files or ebooks or documents or photos or anything else.
