Nope. Theres a reason why corporations and power businessmen/women still use BlackBerries or any smartphone with tactile keys. You simply can't type fast and well at the same time with the iPhone's touchscreen. It may be fun to play around with it, but you try typing an email or texting someone and you'd probably want to make it into an iBrick. I know I did.
