Has anyone had any luck using a Tablet PC as an on-the-go blogging tool? Do virtual keyboards on multitouch screen really work well? Are there other input methods (like Swype, etc) that have worked for you? Is there anything coming out this year you have your eye on? I don't need a tablet to play HD movies, games, or work as a phone...but it would be handy to have one to make forum and blog posts without being as clunky as my laptop.
