SMALL windows tablet?

I'm looking for a SMALL win tablet to shove in a pack while skiing. I need something that is SMALL, has good battery life (2+ hrs reading PDFs and maybe watching movies) and reasonable performance for those tasks only. But it must be SMALL, the 8-inch class is about as big as I can do.

Currently I'm looking at the Dell venue 8 pro, $200 on Amazon:

Thoughts? Alternatives? Think SMALL!
