I'm a long time Android user, well my N7 that I've had for nearly a week is my third Android device.
My first was Sony Ericsson's first foray into Android, the Xperia X10i and you had to be rooted for it to even work properly, well at least to undo the major lag SE's Rachel UI caused the system.
My Galaxy S2 is my current Android phone is also rooted, after experiencing root privileges I couldn't live without them.
Also running a custom ROM on my SGS2, Pure AOKP v3.0 Milestone 6.
As great as the SGS2 is, Samsung's awful Gingerbread theming of ICS is what convinced me to to flash custom ROM's on my SGS2.
For those that haven't used custom ROM's, the likes of AOSP ROM's like Cyanogen Mod and AOKP ROM's make a great deal of difference to the stock AOSP Google ROM's with tweaks and mods making the users experience more refined and enhanced.
After all this I was adiment I wasn't going to root my N7. With a rooted phone and missing the ability to use certain apps that I wanted to use but which root prevented, I decided I wasn't going to root my N7.
I think I lasted 2 days, the two main apps (Sky Go and Barclays banking) I wanted to use aren't atm compatible with the N7 and after installing a few games like NOVA 3, ME Infiltrator & Deadspace and nearly filling the N7's internal memory with game data I decided to to root so I could use Chaifires StickMount.
The rest as they say is history. lol
