I like the idea, not the execution.
Lack of built-in USB support, flash and multi-tasking is a deal-killer for me.
Chances are, if I was using something like that I'd want to be able to listen to an MP3 whilst browsing the web, this thing presumably can't do that due to the lack of Multi-tasking support. YouTube recently announced HTML5 video tag support, so the lack of Flash will not affect YouTube per se, but there's a lot of sites I'm likely to want to visit which will use Flash videos. Lack of support for that would infuriating.
They're going to need to upgrade the iPad dramatically before the Chrome Tablets arrive or they're going to get slaughtered in the market place IMO.
Still ... it's the nicest tablet I've seen so far. I just think they're going to struggle against Chrome OS once it's released; price wise, performance wise and feature wise, unless they make some fundamental changes.
I definitely intend to purchase a tablet of some sort in the future to replace my aging Asus eee PC, but this iPad isn't up to scratch for my purposes.
Ability to run a local web server would be nice too But I doubt I'll be getting that unless I buy a tablet with a full-blown OS unfortunately (which I wouldn't buy, since it kinda defeats the purpose).
