The build of their phones are too inconsistent. I've gone through three different models with peers and some friends report really poor performance and major manufacture defects. Your 9900 may be serving you well but I'm about ready to slam mine against the wall. The fact that it has never crashed on you is miraculous, and don't get me started with that abysmal battery life.
To be honest, even the guy at the store where I bought it told me that they tend to "brick themselves" and that he had to return his. I hope my luck continues.
Definitely agree on the battery life issue. But I don't mind since I'm never far from a USB port.
