I've recently moved from iphone to blackberry (old school 9700 bold for £300 sim free). What it lacks it gimmicks and mindless apps it makes up for being the ultimate comms device for business on the move.
I can wade through and process emails super fast, something that I believe touch screen phones just can't do. Also everything on phone is pushed to me, even after new OS installed it still gets the email accounts setup again as if by magic.
Love the form factor and battery life around 3-4 times that of a touch screen also.....bought the missus one and we can just talk using BBM (no sms), and even fire large video files at each other via it.
Problem with RIM is they don't seem to be good recently at innovating, but I guess if it's not broken don't fix it.
Things I miss about iphone hmmm, not much really, few games but I never really used them anyway.
Will prolly stick with the 9700 till I see totally lag free and matured android phones about (close but imo still not quite there)
The Torch the OP mentioned is just a BB with a touchscreen.... does the job pretty well from experience
