I had the old freeware version for a couple of years but deleted it when I got 8 last year. Once I get 10 (preordered it.. apparently it will be out coinciding with start of MLB season
) Ill back up 8 on DVD after importing it into 10.
With sports sims/games I rarely have more than the newest version I own on it. For a few war games I won I might have 2 or 3 different ones.. and even then I might just save 'saved games' and reload around it when I want to finish.
As mentioned by a previous poster, disk space is limited with digital pictures and transfers from the hard drive camcorder still in editing mode!! Plus my 15 year old daughter has a digicam and like all of her freinds it seems has well over 1000 (Honestly I believe over 2000) pics sitting there. When I tell her to bakc them up, well.... enough of havogn a teenager in the house.
