Acer disappointed everyone by mandating their Android netbook to dual-boot Windows, but it'll nonetheless be interesting to see an Android-ized netbook, even if it's not as cheap as we'd like. According to Digitimes, we'll find out in August. [Digitimes]
I am not sure Linux has to be "like Windows" to avoid returns. Macs don't suffer from this issue, so there is no reason why Linux should. Also, people don't return their BlackBerrys or iPhones complaining they don't look like Symbian.
The issue is that Android or Linux need to provide the functionality people actually use, not those that the OpenSource community, or Google, think they want.
I think this speaks volumes for the likely success of Google OS, for example.
