Wow. I just saw the price of the Macbook Air's solid state hard drive "upgrade". At that price I'll pass. I'll purchase the notebook and then upgrade later, when the price comes down. Reminds me of when I was in the process of purchasing a Macbook Pro, the 4 gb memory upgrade was $700 direct from Apple. I bought the same memory size from Micron for $129 and took the 5 minutes to do the upgrade myself.
