Smaller means more likely to be lost
This LG looks fantastic and the bit about Linux is wrong. Whatever you think XP plus 160Gb disk plus really lightweight etc means this will sell in spades. However the smaller it is the more likely it will be lost, left in a cab or pinched. It needs a data protection tool such as Backstopp to make sure all that 160Gb of data does not become somebody else's.
Criticism of the cost is daft because 3 (and all the others soon) are offering £450 against a data contract so to all intents and purposes it will be for nothing, in fact the retailer will make £100odd on the hardware alone so will market this with gusto. Phones 4 u are already doing it. No price complaint surely.
Remember, as Shaw Taylor said - keep it safe.
