Just to balance up what Johnny said.....Maybe the Mac argument was true years ago BUT I think it no longer applies now.
Hard drives can go down and other hardware and software issues can occur whether you use a Mac or a PC...I know guys who have had major problems with Macs and they are generally not so user fixable as a PC plus fewer places to fix them. They cost a fortune to repair compared to a PC.....Now add that to the fact that Macs are about twice the price of an equivalent spec PC and fewer people have them so less of your friends can help out with tech knowledge and help to use them then I see no real advantage in having a Mac.
As stated previously it is down to your preference and needs to decide which system you prefer.
Possibly it is an American thing. Most Brits use a PC and a higher percentage of Americans use Macs. Still fewer than 10% of computers are Macs so 90% of us cannot be all wrong.
