I've owned 2 blackberrys and for texting, emailing, casual browsing and limited social networking, calendar and all around reliable. It is a handy sturdy phone, they are great. I was (sometime ago) a fan of the type.
But, the thing is, if you're looking for a phone to do more than this, the basic QWERTY is not that great in comparison with androids and iphones. They have all apps available, great browsing, screen, camera, im sorry to say but they are definitely the next step.....
I was a few days in London with my girl and I used her Iphone 4S extensively for browsing stuff to visit (and retrobike too lol), maps, gps, like if I was with my laptop... Even checking my ebank was MUCH easier than to try to get the cursor arrow to press submit on my narrow blackberry...
Its a 9700 Bold II, its dated, but it works flawlessly (with OS 5, course)
My next step will be a galaxy or something..
