Without a physical keyboard, I fat finger everywhere. Swiftkey actually fixes much of this (so much so that for short messages, I use the on-screen keyboard), but if I'm texting a lot or writing a long message, the keyboard is a must.
And don't even get me started about trying to use the terminal w/ the on-screen keyboard. Seriously? One of the sweetest things about these phones and tablets are that they are super-mobile, and relatively powerful. It seems like a waste to not have a decent input device coupled with that...
Disblamer:I also always rocked the QWERTY dumbphones too...
