I've got a Vaio UX which is similar to the OQO and was it's direct competitor. These two were really TabletPCs in a small package. The UX has the same OQO form factor with a much better processor (Intel Core Solo.) Unfortunately it has a passive digitizer whereas the last *production* OQO (not the OLED prototype on eBay) had an active digitizer (much better for handwriting) but the processor was a dog (VIA nee Transmeta.) You are right it does not fit in a shirtsleeve pocket but it sure is handy to have. In winter it fits in my coat pocket. Any other season I carry it on my hand in the fashion that you see people carrying their little digital cameras on a strap. What is handy about it, and important to me specifically, is that I have all the PDF articles that I need and can make annotations on them with the stylus. I have all my notes in OneNote (the only Microsoft product that is any good ) and add to it on the fly. It is possible to have a completely satisfying web cruising experience on these as well. In fact I know people who only use theirs for the web when on the road. In other words, a large screen and a keyboard is much overrated when contrasted with this kind of portability. My case, I can do without a keyboard altogether as most of what I do with it involves handwriting on the screen. The built-in hardware keyboard, along with the TabletPC virtual keyboard and TabletPC handwriting recognition are adequate substitute for those people I know who only use it for web cruising on the go. If you haven't used a full size TabletPC then it will be hard to understand this. If you haven't tried an OQO (with a digitizer) or a VAIO UX after using a full-size TabletPC then you surely will not understand how handy these small factor TabletPC machines are.
