It was the low end 15' and it's awesome. My first Apple Laptop ever! I do have a couple questions though... 1) Does Safari have a legitimate Ad Block? I looked in the ad-ons and the reviews weren't good...any good ones guys? 2) I want to save all my logins and passwords...I'm using 1Password...but I also see something called Keychain...what is that? 3) Is there a way to sync my Google Calendar to iCal? They linked my Gmail to Mail...but I'd like to sync the Calendar too. Anything else I could know would be great!
