Now to post about OS X. OS X in my opinion is a very simple stable OS. Go to the dock, click on the icon of the program you want, boom its up. To install an App, drag the file whether it be from a CDROM or compressed format to your applications folder what wherever, boom its installed.
Now with Apple allowing Windows to be installed whether it be from Parallels, Fusion (vmware) or boot camp is pure genius. Apple is taking something away from Mr. Gates and that is your Windows customer. Apple is saying, "Come get an Apple, oh don't worry, we allow Windows to be installed on our hardware but also please check out OS X." Customer says sure ok, checks it out. And next thing you know, the customer experiences OS X with its applications like iphoto, etc.. and becomes hooked. Its a way of offering candy to the customer but with a little surprise in the middle.
