First to reply here,it do seldom hang and lag compare to Microsoft windows. Can't say it truely virus or spyware
free,but i not much hacker will interested to created by the way. BootCamp is piece of cake,you don't have to find
it driver because it already preload in Mac OSX installation disc.Either XP or Vista.

Mac do have it own DMG installation Games,exp :COD4.But if you wanted to play windows format game you just have
to boot to windows and play it there,currently bootcamp is still the best option if you want to boot windows with Gaming.

Yes,you will have to install Microsoft Office 2008 Mac edition or iwork.In my opinion,i can sense Apple will slowly pre-load
iwork with it ilife together on coming next few years,just my 2cent. Gaming with bootcamp is great actually,even your windows
partition is corrupted or affect virus,your Mac partition will still work without any problem.You can just enjoy both world.

I guess you just have to at least try to have a look on the OS on those retail store,and see how it goes.
