I don't agree. They make wonderful LCD screens and everything else. And their windows phones are actually very good. I just hate their Android side of the business. Android sucks (I've used it for a year, I HATE it), and they are just copying Apple to try to make it better. It won't be better. It still sucks. I won't post all the things that don't work / suck about it as the list will be too long.
Jellybean is leaps and bounds above what we know as Android. However, i do understand your frustration. Before jb, Android was a mess and too many ppl just got complacent and tolerated the lag, reboots and glitches.
I think you should try a jellybean Android phone out tho. It's an amazing os, and a job well done by Google
