I have the E50 made in Finland black if that matters, if you text a lot and you don't want a QWERTY keyboard, then i'd suggest the E65 or N73, the buttons are bigger and softer, these are things i'd look for if i were texting a lot.
I also have the SE K790a and other than just reacquainting myself with Nokia, i find texting on the K790a just seems easier vs the E50 but i text slowly not fast and furiously where i think bigger and softer buttons would be a sensible choice pointing again towards the N73 or E65, E65 being the more 'stylish" of the two.
