It's not worth trying. These tabs are all running old versions of Android these days (version 3.0 is almost out), and until someone comes up with a way to install a full-fledged Linux on it, you're at the mercy of the provider as to what kind of software you can install on it. Furthermore, the non-iPads all still have resistive instead of capacitive touchscreens, which suck. That's one thing the iPad has which is really worth the steep price tag. But I would suggest giving the pad / tab business another year or two to develop sensible gadgets.

A Windows program won't run on them anyway.
