This has probably been asked many times before but is it possible to integrate Fitaly into the TabletPC TIP? Does Microsoft allow you to add TIPs like you can on PocketPC? I'm not sure you could sell Fitaly TabletPC for that much if it's not integrated into the TIP. It's quite awkward to use otherwise. The TIP is pretty good in that it's always available at the right location when you want to enter text. Gecko TIP for Firefox helps but does not work for other applications.
Another useful feature of the TabletPC TIP is that it's scalable, so instead of providing 3 different sizes the user can scale to the size that works best for them.
