ASUS Eee Pad official: Intel CULV processors, Windows 7, and a 10-hour battery life -- Engadget
10", $399, Windows Embedded Compact 7 (?)
12", $499, Windows 7
camera, USB included...

from my experience, windows 7 on a asus netbook is SLOW.
touchscreen netbook (T91MT) with flash-drive and 2GB RAM

maybe the CPU in eeepad 12" will be faster,
or microsoft will "trim" windows 7 for tablet...,

windows embedded compact 7 is most likely OS of Windows Phone 7
so eeepad 10" may in fact be based on equivalent of apple ipad,

this means microsoft is in fact replacing windows ce
by trimmed version of full windows 7,
similar to what apple has done with iPhone

This evolution may bring mobile apps on desktops/laptops!

Since windows phone 7 will have silverlight based apps
managed in similar way iphone apps are managed
and it will run on same core os as any windows 7 computer
This will open doors (ok, windows) for apps on desktop/laptop.
In fact, Microsoft Office is one of first such "apps"...
