I have a bold on my hands right now, and while it is relatively nice device, it's web browser leaves a lot to be desired. The rendering performance is not up to par, zooming in and out, and overrall navigation are not in the same league as the iPhone.
Of course, email/messaging, typing, are excellent. The screen is really nice too.
So, it all depends on what do you use your main device for, email, or web surfing.
Coorporate people, probably care more for email, while normal users, about surfying, apps, and shiny things.
Since the growth in future of smartphones is more in normal users, and not coorporate, the iPhone will soon eclipse BB, and it will start eating it's turf.
I honestly think that RIM just don't get customer stuff. I remember a little over two years a go, argueing with one of their engineers, and they were making clear that mp3/video playing is not a big deal (and they didn't care for), and that cameras and external memory are security risks.
Well, these are the same things that normal customers want. Eventually, reluctanty they are coming to their senses, that even the Coorporate devices are used by PEOPLE, that actually kinda care for fun things too. If iPhone gets their email up to par with BB, then they will soon starting eating Rims lunch.
