Which defeats the whole point: I'd still use my Xperia Pro with a built-in slide-out keyboard, except app bloat makes it useless (Google Play now clocks in at 190 MB? And this is representative of the other apps.) It was perfect for touch-typing "on the bus", as you say: if you have to fiddle with accessories and perhaps get a coffee table to put them on, you might as well lug a desktop computer with you ;)
