brits get to pre order cause their not so lazy as their US counter parts and actually probably googled it. Meaning, theres probably a place in the US whos pre-ordering but everyone is to lazy or too worthless to find the place.
It's a marketing gimmick. Or at least I think it is. They sell the Core 2 Duos higher than normal, get the processors from Intel, and finally give it to the pre-orderers. Meanwhile, they are making bank from the people who pre-order.
The only problem is if Intel doens't get out that many Core 2 Duos to retailers. Hopefully that won't be the case.
