The BBC have an article discussing how there is an issue with older Word documents becoming harder to read as older versions of Windows and Office are made obsolete.
Here's the accompanying movie.
Lovely - so the solution appears to be that the BBC demonstrate how cool Vista looks as opposed to older versions and then proceeds to demonstrate the need to use MS Virtual PC in conjunction with an ever increasing selection of Virtual PC images just to read a text document. Have they heard of Heath Robinson?
Of course - if you really want to be able to read some important documents after a decade or two - you could choose ODF, OpenOffice, StarOffice, Lotus Notes 8, Neo Office, etc....who mentioned license fee?
