I don't use Google+ much because nobody else I know uses it. If it were more widely used, I would use it actively. With YouTube integrating it, it may get more use, but currently, there's a lot of backlash.
I like Android, but I don't LOVE Android. It always slows down when I'm trying to do something. It isn't that I'm on an old device or version either, as it's a Nexus 7 with 4.2.2, but I just can't seem to use Android much due to sluggishness.
As a geek I really want to use Android, and it's something I want to tinker with a lot, but there is always some issue that stops me from diving deep in.
