I'm planning to get a new Macbook Pro, and upgrading my iMac in the near future. In making the big leap to Leopard, I am going to upgrade my router to at least the AEBS. But I'm not sure what the best way is to take advantage of the Time Machine function. Here's my take on the situation: Time Capsule Pros: all in one solution Cons: I'm stuck if one day I need a bigger drive, or need to replace it. AEBS+USB drive Pros: Easy way to upgrade/replace drive if needed Cons: Extra device and power plug needed Using a drive on my Linux fileserver Pros: Most cost effective and easy way to upgrade/replace drive(s) if needed, can set up RAID1 for extra redundancy. Also, I already have this hardware. Cons: Not officially supported, but apparently can use the "defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1" tweak to get this going. Which would you do?
