Bad looks. Laggy, onscreen buttons and things all in the wrong place, not well thought out etc etc.
Yes
No, but very noticeable
I'd say off and on for a year.
Bad looks? You might not like the style, but subjectiveness aside,
it seems fine to me.
...well, I guess the fonts are a tiny bit better in iOS.
Laggy? Define lag for me right fast. I've only got a limited amount of time in with the newer versions of Android, but the only thing I noticed during the time I spent with it was that it would occasionally get a framerate hiccup when loading something. And when I say occasionally, I mean once or twice in about 15 minutes of use time.
All in the wrong place? Not well thought out? I always have to laugh at this one when comparing Android to iOS, because...well...the settings menu in iOS is a cluster**** of a mess to navigate if you don't already know where everything is. This isn't at all what I'd expect from Apple, considering how clean and well organized everything in OSX is.
The rest? I chalk it up to "I'm used to A, so since B is set up differently, I hate it by default". I dunno if that's the case with you exactly, but that's generally how these things go.
...some specifics would be nice here, of course. Gimme some examples of what's laid out so badly about it.
Getting down to the basics here, I just can't see why some people think it's nearly unusable garbage. You might've had a case back during the Gingerbread Man days, but now? I'd put it about on par with iOS as far as attractiveness and ease of use go.
