My Treo 600 finally got in yesterday. It feels amazingly tiny (good in the hands) and the keyboard is squished, but fairly usable. More review stuff later. Interestingly enough, although it feels much smaller, it’s actually not too much smaller than my co-worker’s Treo 300. Here are the dimensions as compared to my Sidekick:

Kevin Werbach made some observations on the size in his recent article in The Feature: The Triumph of Good Enough.
