PC World (in the UK) are selling the old 2.66GHz 15" model for £1,149 (rather than £1,499 for the new model). The differences between it and the new model are summarised below (as I understand them) Battery: Old: 5hr, New:7hr non-swappable Display: New: Better colour gamut (apparently?) Processor: Old: 6MB cache, New: 3MB cache Card bay: Old: Express34, New: SD Of the above only the battery life is of any relevance to me (unless the display quality is really that different?). The SD card would be marginally more useful than the Express card. So is the new model worth the extra £350?
