Yup, I'm using an EXOPC Slate right now (essentially exact same hardware as the WeTab). I got it off eBay refurbished for around $350 a few days after the CP was released, loaded it up, and it's been working great ever since.
Note though: as i did a clean install, i had to reinstall a little app called 'Millennium' to get things like auto brightness/screen rotation to work properly.
Also, while overall it does work real well, being pretty low-spec'd there are times when the touch becomes a bit unresponsive for a few seconds which is annoying. Otherwise, its an excellent (relatively cheap) option to get your hands (literally) on w8!
Let me know if you have any other questions.
Also, anyone else out there with an EXOPC/WeTab??
