I will admit that it has a great interface for backup copy. The ability to browse through history of files is pretty neat. MS will never be able to come close to it. But there are a few limitation that just irks me. For example, the other day, my brother wanted to access a file on my Time Capsule from his iPad. I said "sure, it will work." ...thinking they are both Apple products and Apple is big on integration. Well, after 10 mins of fuddling around, I finally consulted Google for an answer. Turn out, it doesn't work that way simply because Time Capsule is only meant to work with Time Machine...and that's about it. You can drop files onto it, and you can access them on home Wi-FI network. But once I step out of it, it gets tricky to access files remotely. Nowhere on the manual shows you how to do it either. So Apple apparently doesn't want people to use Time Capsule that way. Speaking of being a soulmate to Time Machine, it's an overstatement really. Because once you step outside of your home network, it just doesn't work. I am an accountant frequently on assignment to various cities. The inability to backup to Time Capsule on the road has me thinking this in hotel " Hmmm, maybe I should make this change to the file after I got home". Sorry, but this is not cool.
