Hi everybody, First-time poster here, configuring a mac ... At this point in time, I don't think I'll be able to afford the SSD. Rumor has it that it will be bigger and cheaper in the future. If I remember correctly, isn't the hard drive swappable according to Jobs? So that later on I can swap in a big fat SSD if I only go for a 7200rpm drive right now? Or must I already have an SSD to swap in a bigger/badder SSD later? Many thanks.
