So my MacBook Air is in the shop to get the core shutdown problem remedied. In the meantime I am using my MacBook. I still like my MacBook, but boy do I miss the Air. Surfing the web without multi touch seems arcane, it feels like a brick, and ah I remember the creak of the screen, and the worst of all....the fingerprints and smudges on the black case. On the other hand... all of my content is here due to the bigger hard drive. It really is amazing how much less apt I am to pick it up and bring it along even though it is only 2 pounds heavier and a little thicker. The difference is actually significant to my habits.
