Mike Schramm, of The Unoffical Apple Weblog:
Twitterific lead the charge way back when, but Tweetie came quickly after and then the flood gates were opened. But now, a late and unexpected challenger has entered the ring: Twitter themselves.
I haven’t played with the new mobile version of Twitter, but I totally agree with Gruber:
This would have been great two years ago, before there were native iPhone apps. Still might be great for Android, Pre, and Symbian phones.
