I'm not surprised. Asus's response to the iPad has been to stop improving their netbooks. The product they're shipping now is in no way different from the one they were shipping six months before the iPad shipped. It isn't even cheaper. Maybe the battery lasts longer, but they maxed out that spec when they hit 7 hours use per charge.
Meanwhile this leak re a Google/Chrome OS/Verizon tablet shipping in November sounds like just what the doctor ordered. I'll buy one for sure if it's less than $500. I love buying new cool gadgets. Too bad Asus isn't offering any.
Update: Lots of interesting comments on Hacker News.
