Bought a iMac 24in two months ago and I'm running Windows XP in 'Parallels' (runs better here than on any PC I've ever owned). Pros: Easy to physically install, setup just works, tons of included full license software, fast, always works on my mouse click (never see an hour glass or an un responsive mouse), comes with everything (little aftermarket hardware to buy...because you don't need to), 24in screen is awesome(can run my XP session and Mac apps and see everything), did I say fast, very quick boot-up time (even XP boots-up fast), network setup is unbelievably easy, no antivirus required!, Safari is and excellent Internet browser and you can get Firefox for Mac free (I prefer Firefox) and stuff to control your apps that Vista still doesn't do.
Cons: takes getting use to screen controls being on the right and drop menus always at the top of the screen separate from the window, had to buy Microsoft Office 2004 to get Word, Excel, Powerpoint and Entourage(Outlook for Mac), Quicken version for Mac is very bad (returned it) and I run Quicken on the XP window....works great, many speciality apps work only on Windows, price of unit, you have to buy a full version of XP or Vista.
Designed from the user...period.
I never though I would say this (way to many years of being a MS fan). Once on iMac....you'll never go back.
-- Yes. (Why?)
-- Maybe. (Why?)
-- No. (Why not?)
-- Not switching, but using a Mac and using both OSes.
-- I'm already a Mac user! (Are you happy?)
-- I'm thinking about it. (What's the hold up?)
-- I'm not using either. (What are you using?)
