Nettops need more power?

At theONbutton, Neil Berman is less than thrilled by the low processing power of nettops:

Whilst we are eternally grateful to Asus for the original EEE PC and the Netbook offspring it spawned, why do OEMs continue to think it’s OK to package an Intel Atom with GMA950 graphics in a home PC?

Apart from the potential electricity savings why would a sane person ever say, “I’d sure like to have an underpowered home PC which will struggle to play YouTube vids”. And given how much longer this PC would have to be powered-on to complete tasks which an Intel CULV chip could complete in a fraction of the time, are there really power savings there at all?
