I don't hate it, but I'm kindof disappointed.
Surfing the web is frustrating as nearly every website wants to go into mobile mode. Some are hard if not impossible to use normally. While the youtube app works great, trying to watch flash based webinars in a webpage has been les than fantastic. Some don't work at all. They don't forbid screenblanking which is annoying, and they tend to restart from beginning when I get the screen lit back up again. Very annoying. I can't edit my wikipages wikis. The few games I've tried seem to work OK, but I didn't get my phone for games. Some apps annoy me with filesystem layout restrictions that conflict with where I want to put things, such as some PCB gerber viewer insisting all gerbers go into internal storage, not on the sdcard. Dumb... Didn't work with the gerber I threw at it anyway. Input gets weird at times, such as most apps auto-capitalizing for me but others not. one app somehow ate shifts so I could not do capitals at all. Weird... It feels like I have to use one web browser for this site, a different browser for that site, and a third browser for some other site. I should not have all possible browsers installed just to get to 80% of the web.
Very much looking forward to Ice Cream Sandwich for my Droid4, maybe that will improve things... Maybe not.
