I'm looking to get the AEBS for my apartment. However, will the newer model of AEBS make a difference with the gigabit ethernet if both my fiancee and my laptops are wireless? Isn't the principal difference is that the gigabit is that much faster when going hardwired through the router? I'm going to plug in a hard drive for wireless access, along with a printer. Having a gigabit connection shouldn't make a difference when using these things right? (assuming the hard drive and printer are USB) I guess since I don't plan on being hardwired into the ethernet connection with either her Macbook or my Macbook Pro, the gigabit connection shouldn't matter correct? There isn't anything else that I should necessarily need the newer model with gigabit for is there? Thanks for the advice...I'm just looking to make sure of this before I take the plunge... P.S. What would be the main reason for using either 2.4 ghz or 5 ghz? I can't figure out why one is better than the other?
