I recently tried out Windows 7 and I have to say, I really like the application management features that they have come up with. Then I heard about "Marble" and it made me think: Is a new interface, such as Marble or whatever it's going to be called, all about the looks or could it have something to do with application management as well? As far as I remember, Marble was described as a new look and feel of OS X. I'm not trying to argue over whether Windows 7 has better navigation tools than OS X, I'm just saying that I was impressed (seeing as I hate XP, that says a lot) and I'm thinking that Apple probably has to do something to fresh up Exposé or even better, come up with something new. But what do you think? Could Marble contain more than looks?
