Ah, if only we had a crystal ball. ;o)
I find it difficult to believe that laptop prices can fall much further than they are now. They're incredibly cheap as it is, and I reckon that retailers are so desperate to achieve sales in the pre-Christmas market that they will already have cut their prices to the bone.
The marketing men will, of course, have marked up the prices of one or two 'headline' products for 28 days (as the law requires), in order to be able to claim a price cut in the January sales, but in general I don't believe that like-for-like prices will be any better next month than this.
