I know I know, this has probably been discussed to death. I'm getting my wife the 11-inch MBA for Christmas and I really just have two questions. Should I upgrade to 4gb ram? And should I get the 128gb ssd instead of 64gb? Let me tell you the use cases. Right now, my wife has a 4 year-old 13-inch HP 1.6 C2D w/60gb hdd, 1.5gb ram. But she barely is on it except to sync her new iPod Touch. To be honest, she uses her iPod Touch for virtually everything-browsing the web, facebook, etc. So I'm thinking that I might not even need to upgrade the RAM. Thoughts?
