I bought an nTablet for a fair bit less than that (same reference design as the Tegatech Tega v2 and Viewsonic 10, among others) running win7, and it suits my needs nicely (Froyo on big tablets should be avoided like the plague, and 7" is too small for my needs). It's pretty much all singing, all dancing (usb, video out, micro sdhc port, wireless n, 3g modem, win7) at a comparatively moderate cost of £430.
Additionally, a major factor is that it was available to actually buy and really genuinely own several months ago, rather than a lot of semi vapourware "releases" or the current CES crop that wont be available for 2-6 months.

Of the CES releases though if I was looking now, in the android segment it'd be a toss-up between the Xoom and Asus Eee Pad Slider, both running honeycomb (which seems infinitely more suited to 10" screens and tablets in general than Froyo), and it'd be a pretty tough call - The Xoom seems to be the generally slightly more impressive device, but the Asus has a slide-out hardware keyboard, which would be a big bonus for me.

The Eee Slate doesn't really seem comparable to many other tablets, as the $1000 price tag puts it at the very top of the price range, almost certainly way more than either above Android tablet will go to, and with very high-end specs to match.
If I literally had $1000 to blow as I see fit on an upcoming tablet though, it'd be an Eee Slate.
