No real problems here.
This to me sounds like noise made on behalf of companies yet to announce a quad-core product (or 5-core if you want to get technical about the Prime's abilities).
I think I may have had one reboot what it was on and I wasn't watching it, but it's never rebooted infront of me. Still it's nice to see Asus supporting their customers in a prompt and responsive manner. Shouldn't the media be focusing on that, rather than trying to dig up any old shit to beat them up over?
