Do you enjoy using Android
In a word: Yes.
In a bunch of words: Being a Linux-only person, the moment I heard about Android I knew it was for me. (In case there's an Android user out there who doesn't know this, Android is a Linux.)
Because I'm used to having total control of my computers--in ways other OS users can't even imagine--it's important that I can do things, like customize the hell out of my devices, that other mobile OSes lock down and don't let the OWNER do.
Rooting was fun, what with giving me full access to the Linux guts of the device, but is no longer necessary. For me. It's one of those 'YMMV' things.
Using Android certainly is enjoyable, even when there's no conscious thought involved about it being enjoyable. Doing what I want or need to do, quickly and painlessly is enjoyable! The time spent fully tweaking/customizing a new device--which is considerable, due to how much I do--is well worth it, in terms of efficiency and ease of use, in the long run.
I must add that I'm gleefully happy Linux is now the most-used operating system on the planet, aided in no small part, of course, by Android. Window$ users who had the WOEFULLY wrong idea that Linux was command-line only, or ugly, or difficult, etc., are now happily using their beautiful, GUI, easy-to-use Linux devices. Gotta love it!
