Hi all, I will be visiting the UK in September, specifically York and wanted to grab a MacBook Pro 13". However, I also want to upgrade the hard disk (scorpio blue 500 gb?) and ram to 4 gb. Could anyone tell me where I can get these components? Online shopping won't work for me as I'm not a UK resident...is there a brick and mortar store I can go to? Currys and PC World don't seem to stock these things! Thanks!
