Last month I bought the HP tx2000z for less than $1000. There were all sorts of deals like free shipping, free webcam/microphone/fingerprint scanner, free RAM upgrades, free hard drive upgrades, free Bluetooth upgrades, etc. Of course I shopped around and Tablet PCs with similar specifications from other manufacturers were more than double the price!
Just about everyone I’ve told about this has quickly picked one up for themselves. Typical configurations include dual core AMD Turion 2Ghz CPU, 3GB RAM, 250GB hard drive, DVD-R with Lightscribe, webcam, fingerprint scanner, Penabled Wacom digitizer with touchscreen (pressure sensitive using stylus), 12.1 HD widescreen, etc. The price has since gone up to a bit over $1000, but it is still quite a deal. That also includes Windows Vista Home Premium with Windows Media Center, and a Media Center remote that fits in the Express Card slot.
While it may not be the top-of-the-line Tablet PC, it is much better than my old TC1000 and much more wallet-friendly.
