Interesting observations from Marc Hedlund, who’s owned “one Newton, two Blackberrys, three Palms, and three Treos”. He praises the iPhone’s network threading, but dings the keyboard:
The iPhone keyboard blows. Let’s not mince words, here: text input was better on a Newton. The keys are way too close together, full stop. The auto-suggestion works okay if you’re typing dictionary words (and not, say, street names, as in the Google Maps app) and if you’re in a context where typing space to accept is useful (in URLs, for instance, there is no space bar).
