7.3 v. 8.0 dual boot

I just bought 7.3 Personal a few weeks ago and now 8.0 is out. I'm thinking about dual booting my desktop and my biggest question is the new Yast -- since 8.0 advertises co-habitation with Windows, I was wondering what the 7.3 install would be on a Win ME system (gee, wonder why I would want to try linux??). Or, should I just go get 8.0 (which makes me unhappy since I just bought 7.3 -- talk about timing!) TIA
