Im a tech at a school board and work with both PC's and Mac's
We go thru this same debate.....
It comes down to user needs.....and what they are willing to pay and how much knowledge they have about computers.
In the elem schools we run pretty close to all the same apps on both platforms. The PC's break down more....but are easy to fix. Fewer Macs breakdown but when they do....its expesive to fix.
We have never experienced a virus with a Mac....and that cannot be said with PC's.
But again it comes down to your preference.
For me....for users that have very little knowledge about comps.....you cant go wrong with a mac. No blue screen of death.....no maleware..viruses (yet)
....the maintenance is minimal.....and alot of users nowadays ...thats all they want.
If your into gaming.....and you want a computer to have the ability to easily upgrade....more software.....etc....and you have some knowledge about computers and dont mind giving it some tlc every once in awhile then the pc is great and cheaper.
You can probably buy two mid level PC's laptops for the price of the Mac laptop......My Girlfriend ended up getting a PC......my nephew bought the Mac.....its all about preferences....
