This is the hardest decision for me. Do i go with a 4GB setup 11.6 inch laptop or spend the extra 300 to get. better cpu, better battery life, SD reader and More screen re-estate. I don't want the macbook air to be too fast that it will replace my 2007 macbook (which will soon be a mac-mini 2.4GHZ). How are you guys liking your 13 inch vs the 11.6 inch? I see more people at the mac store going nuts over the 11.6 inch.
