Ah I see the disconnect. You're talking about Android running my microwave. I was thinking about consumer electronics like phones and tablets.

While I agree a lot more devices will be running a more complicated OS with increased capabilities in the I future I don't think it is a foregone conclusion that it will run Android. Android is primarily used on phones, tablets and TVs because of explicit design choices made. Perhaps they will position themselves as a generic OS for electronic devices but they have some work to do before that can happen.
