On a lark, I signed up last week for Google's CR-48 pilot program.
Well, so far it's really cool. 90% of the time, I'm checking email, surfing, or doing stuff online. I share docs on google docs. I use google calendar. I post pics with Picasa. I'm a self confessed Google head.
The only complaint so far: Netflix doesn't work. But then again, it doesn't work on my pre-Intel iBook either.
