Coming back to read what others have added, I now see the MobileTechReview of the EP121 that I didn't notice before. It does a good job of pointing out the high points of the tablet.
She said that the USB slots are "fiddly" - they're a royal pain! And if you noticed, she had trouble getting the stylus back into its silo. These are minor details, but they're the kind that could just drive you crazy in a short while if you're the type that gets driven crazy by small details!
I do actually like the thing, but it's so
expensive! But the specs are good, like a 12" laptop where someone forgot to attach the keyboard. I used it for a short time with that bluetooth keyboard and a mouse as my desktop computer, and that worked out well. It just seems that for that much money they should give you this year's Core i5 instead of last year's.
So I haven't done much with it as a touch tablet. I had some accuracy trouble when using my fingers. Maybe there's an adjustment for it. But no matter how hard I smashed down my finger onto the screen, the area selected (which shows up as a target) was tiny and usually just above or below the active spot of what I was trying to hit.
If that could be made larger (and it seems like it should be possible), then I'd say my touch experience with it was just fine. And as HansTWN said, the stylus certainly works in Win7.
I have a friend who's an amateur cartoonist and swears by her iPad. It's true that there aren't many options available to you, but there are a few ... enough so that your choice kind of depends on your "application," meaning both what software you want to run and what your intended purpose is.
