I have been using Macs (or Apple computers) since I was 11, and I'm 32. You will never regret your purchase.
Also, as I did with many friends of mine who were die-hard PC users and now are devoted to the Mac, I can offer you my help in everything you may need. My MSN Messenger is available in my profile. You can also find me via iChat (I think AIM for PC also supports it) at
agustin.ocampo@mac.com <– this is not a mail address but an iChat screen name; I will not be able to retrieve any mail written to that address.
