Well in my computer shopper mag the current best buy is Dell XPS17 (£699) (4gb ram, i5-460M) but that doesn't have your ExpressCard thing-a-ma-boo
Best one I can find with expresscard is Lenovo IdeaPad Z560 (£500) (2gb ram i3-350m).
So no quad cores yet. I'll have another look when I'm not falling asleep...
Infact only quad core i can find is Acer Aspire 7551G but £780... (AMD Phenom II X4 N930, 4gb) but not expresscard
For certain you have to be lost to find the places that can't be found. Elseways, everyone would know where it was
