Yea, I would like to know answer to this as well. Why Apple won't make an official statement regarding to that firmware? At least some people will know if stay with 1st generation TC or go with new one instead.
Oh, I meant more towards the new features. Got it up and running...want to look at some documentation. On initial observation, I take it that only one mobileme account can be logged into it? I logged my wife's account in and it dropped mine.
Web Browsing through my original Time Capsule seems a little snappier after the update, not sure if this is because of the wireless being improved or just the overall performance, but I defiantly see a difference.
