Okay, I'm sure this is a dumb question, but I'm too old to care. If I buy the 11" Base Model ($999) and after using it for a while I find that the 2GB of memory is too low, is there anyway to get additional memory added or am I simply out of luck. I know I should pay the additional money and get the 4GB model, but frankly I'm having a hard enough time justifying spending $999 on a laptop as it is.
