are you aware of the asus-1015? i got one recently, and it runs opensuse linux fine, has a celeron chip (appears to support virtualization, though i haven't tried yet; is missing some SIMD instructions that make matrix math slower), and similar size and screen to this (but it's fatter and plastic). i installed a 60GB ssd (comes with spinning disk; disassembly is somewhat painful; seems to fix any issue with the limited 2GB memory). not sure what the battery life is, but i wouldn't be surprised if it were close to 6 hours if you're not doing much heavy computing.
