Step 1: dont spend hard earnt money on a pc when you can get a shiny new silver mac FOR ONLY DOUBLE THE PRICE !
Step 2: Make sure you watch
this
Step 3: Well if you suck at all things technology and actually click on pop up adds that say "you are the 100000th visitor. Click here to become president of Australia. This is definitely not a virus." that yea you should probably buy a mac.But otherwise if you don't screw up completely pc's are fine. I've had my laptop for 5 years before I finally got tired of it. And no it didn't break down.
step 4: don't follow step 5
step 5: follow step 4
step 6: Dont fall for the "oh mac has much better software for video editing and blah blah" stuff. PC's have just as good and better software for everything imaginable. You don't hear a pc guy saying "oh but windows has Microsoft word" and that's because mac has a version of it as well. Even if you dont want to pay for the software you can always just pirate it....i mean buy it off e-bay *wink*
