Hi, I decided the put up my base 13 for sale. The allure of the 11 is too much for me So I've decided to go with the base 11 or base 11 with 4GB ram. The problem is 4GB is not available in store, only the ultimate that will cost me $400 more than the base. So I can either get the base 11 today or order the base 11 with 4GB online and wait a week or so. What to do? This is my secondary (fun) machine. I have a 27' imac already and I'll just use this one for couch surfing, social networking, emails, and minor iPhoto. Will the 2GB suffice or should I bite the bullet and wait a week. The $100 is no big deal at all. Thoughts?
