Mac all the way. You can't argue against Mac if you haven't used a new one for a long time. I've used both, PC for 13 years, Mac for 1.5. No competition in my mind. Mac is so much better made and thoroughly well designed, and innovative.
You can do that? I don't see any point in it though.
I personally like the Mac's keyboard. The keys are made out of rubber, I presume, and it feels "clean". There are similar computers with keyboards like that but not exactly the same.
Both have there places in the world and sadly both have there fan boys, I have to work with both systems on a daily basis and yup, I would give the average user a mac everytime as its much harder for them to get infected and messed up. Notice I said harder not impossible I see my share of crashed macs but at other times you can not beat the flexibility of the PC
