All Vista Versions to Ship on Single Disc

A report on CNET News appears to confirm a rumour that has been circulating for a while, namely that Microsoft will be shipping all versions Windows Vista on a single disc. A feature called Windows Anytime Update will let users upgrade from within their current version, so rather than having to buy a new disc you simply pay the upgrade price.  Windows Vista will be available from January in the UK and there will be five different versions: Home Basic, Home Premium, Business, Enterprise and Ultimate. Vista will also be available in 32 and 64-bit versions, though these will still be sold separately
