All-in-oneS? WTF
I do not think they will overtake conventional pc's. Tower PC's are popular because you can re-use parts that will fit in any other machine, even built by different manufacturers ... the all in ones use laptop technology - which means you can migrate hard drives, ram, wifi cards etc pretty easily, but try and replace a faulty graphics card, right!
All in ones are bad for the environment, because when a chip breaks on the mb, you are often better off dishing the whole thing and getting a new one because the prices of the mobos will be/are very high. Then again, companies buy small form factor Dell's and the like already, with weird moobos etc ... I never understood those cretins who spend our hard earned profits on crapware like that. Thank god I work for a company now where the syssies have half a brain ... and we get propper towers ...
In the unlikely event of the sale of all-in-ones taking off, I see Apple getting the largest share of that, anyway, since they have decades of experience in the matter and when it comes to design, they are the firm that cannot be beat. Asus, you fail and even if you end up being right, you'll still fail ... LOL
Mines the one with the FreeBSD manual in the pocket ...
