blackberrys sucked hardcore, and a bt keyboard would be well and fine if I can find one that fits the phone right, not going to carry a full sized keyboard on me... although I would text faster than anyone, except the asians.
I went from physical keyboard to non last phone, and I'm finding I'm sorely saddened by the utter lack of physical keyboard phones available now. The Droid 4 still seems like the best option, which is what my wife got...2.5 years ago.
There's a Blackberry meant more for the non-business demographic, but its reviews are so-so at best. Everything else looks like it sucks butt too.
I would kill for current technology put into the body of an original Motorola Droid. That thing was great, and for being a slim little phone, it was hefty as hell. I loved it.
