I'm just wondering, would the switch be difficult,
and take a long time to get used to? Or is it not
that difficult.
The switch is not difficult, it's very easy and you will not regret it.
I did the switch last christmas when I bought a Mac Mini on my trip to Dubai. back home the first thing I did was to power it up - and wow it was just very easy and the OSX is just a beauty. I did some test, did find much better programs tha thos I used on my WindowsXP.
I'm a Windows supporter so I need to have a Windows PC at home, but now it's sold, and I have bought a 20" iMac C2D. So if it comes over me, I can boot it into WindowsXP. My wife is now using the Mac Mini (she loves it) and my daughter has bought a used iMac G5. So my hole family have done the switch.
Remember: You are allways happy in front of a Mac. 🙂
