To be honest, I suspect a lot of the netbooks sold with Linux today actually end up running Windows. I think current Linux Netbooks are actually damaging the reputation of Linux, because the manufacturers install shitty niche distros. Why they can't just band together and pay Canonical some money to optimise Ubuntu to small resolutions I will never know. (or do that for any other mainstream desktop distro)
If there's no way to install Windows, then I suspect they're going to be a tough sale. Also, no flash player and therefore no YouTube. Fail. (don't talk to me about the YouTube apps on the various Apple devices. Apple "get it" a lot more than ASUS, MSI, etc ever will)
