I am a bit confused. I am looking at the specs for the AEBS and TC. Is the only difference being that the TC adds a built in hard drive? I have a Macpro desktop and Macbook pro laptop and want to be able to back up to both. I already have a Netgear wireless router and am only backing up to a portable drive on my desktop. No backup yet for my laptop but it is not critical. Here are my 2 scenarios. Buy a Time capsule and be done. Or buy an AEBS and choose any number of other external hard drives available. My concern with the TC is failure. I keep reading at the Apple support page and reviews for the TC and some say the quality and longevity is very poor and others have no problems whatsoever. So what are the advantages of the AEBS over the TC? Would it make more sense to go with the AEBS and purchase a drive or just Time Capsule?
