The surface Pro will be a very sweet TabletPC but a bit on the pricey side because it it a premium, Core5-based PC.
Other quality devices based on Intel Atom CPUs worth looking at are:
1- Dell Latitude 10 $699

3- ASUS VivoTab Smart and others

The VivoTab smart is essentially a Netbook made tablet and lists for around half of the Surface Pro. Lenovo has a couple of interesting options, too.
The beauty of Win8 Tabs is that with Surface providing a benchmark, the OEMs are *forced* to get creative.
Expect to see more interesting products, like this 12in Dell XPS 12:
