Is it finally about time to drop my blackberry?

I've been loyal to RIM for years but lately with all the updates(rarely does a day go by when I don't have an update) and unexpected glitches and freeze-up I'm losing patience with my BB. I'm also starting to believe that update is blackberry code for "you use this app too much so we're going to render it useless". I've heard that RIM is going to launch a new os that will fix all these problems. I miss the reliability of my older BBs and wonder if I'm gonna experience the same trouble with the next gen BB as I've had with this new Bold or should I just move on to an i-Phone
