Hi, I'm a Mac neewbie and I've decided to take advantage of the education discount and get a new Macbook, Ipod Touch and printer. I just a bit confused on what version to get. What's the difference between the combo and superdrive? Can you burn DVDs on both? Also if I want 2GB Ram should I buy it from Apple or have my tech savvy dad add a 1GB himself? If the most complex programs I'm using on the computer are Photoshop and maybe Final Cut Express do I need the 2.4GHz version? I'll mostly be using the computer for photo editing, typing documents and browsing the web. I really just want a decent configuration for a good price. Any advice?
