I've used both. I am full mac now. I would say the biggest plus is how the computer runs say, a year from now. I have an ibook laptop that is probably 5 years old that runs circles around my wife's year old HP desktop. Not that is is more powerful or anything, but the HP is so gunked down with virus protection and the like, that it takes forever to boot up, runs slow, crashes and is a headache in general. We have gone thru I don't know how many wireless adapters to get a good signal from our network, yet the ibook can get the signal across the street in my neighbors backyard. It is a little tank. I know have 3 macs and love them. The downside is they are different. Honestly the #1 problem I had with the switch was the simplicity. How do you get programs off? Just throw them away. How do you set up wireless? Turn on airport. Don't I need to defrag? Nope. That was the #1 thing to wrap my head around. I've tried to get my dad to switch, but honestly why waste time teaching him a new way of doing things when he just got used to Windows. Heck, he has a new imac and runs windows on it. He complains how slow it is and why does it lock up...have to explain to him that a imac with windows, is a pc. My vote is for Mac, but I am biased. Good luck!
