@OmSigDAVID,
they're very reliable machines, and seem to have longer shelf lives than pc's, ie they aren't obsolete by the time you get home, they do have disadvantages, they are not a great gaming machine, the number of games playable on pc's is much larger
you can also run windows on a partitioned hard drive (you do need a full copy of the windows program, not an upgrade), and you can get microsoft word for mac if your familiar with that program and want to continue to use it if you switch platforms
