I went from official .75 to official .148. Not as buggy and camera is a little faster. Biggest issue for my wife and I ( both have storms and upgraded OTA) Battery life not as good as .75. That is a huge disappointment. We are both fairly light users also, very frustrated after waiting this long for the "official" upgrade and now batt life worse than ever!
Wife and I upgrade and had some initial problems, but pulling the battery out and popping it back in solved all our issues. Only thing I couldn't fix was the trial period for Word to Go was cut short and I can't reactivate... and I don't want to buy it.
The touchscreen seemed more responsive from the get go and the browser felt overall faster, so I'm pretty pleased.
