I have joined this site a while back. This is my first post. I read posts frequently & after reading a lot about Mac. Finally built the courage for the purchase & switch. I still windows as I work in IT. I have to admit for a 12 year old Windows user. I am very impressed about OS X. I am on Snow Leopard as my first OS X of mac use. I am really digging the no drive letters among many other things. Happy first time Mac customer. My previous machines were all Dell & HP. I was very happy with them. The MacBook Pro just caught my eye now the savings has begun for an iMac & iPad next to complete the trilogy.
