I just bought a new MacBook and I love it. I'm slowly getting all my data moved off my old PC. I'd like to get an external hard drive for time machine backups and also for a little extra storage. I'm trying to decide whether to go with the Apple Time capsule or an external hard drive with an Ethernet interface, like this LaCie drive. Will the LaCie drive work with Time Machine over my home wireless network. I know that I'll want to hook it up wired to begin with, but I'm hoping that wireless will be enough for regular backups. I'd also like to use the hard drive as an NAS drive. Any thoughts?
