Customizability WinMo vs Android

[Zori]

Hey everybody!
I'm a Sprint customer, having had my touch pro for over a year now. One thing I really love about WinMo is all the customization I got to do with it, always changing the interface in some way. It always felt like I had a new phone to play with. Now with the Evo 4G coming out, I'm getting super hyped about it. My only gripe is that, with my very limited experience with Android, it seems like they all function, more or less, the same. I know this will come with Sense which will add something different, but can you have drastic changes like in Windows? I have been trying out XDAndroid on my touch pro and it got kinda boring kinda fast. Probably due to the lag and horrible touch, but still.. Is there anymore to Android then what's given by the seller? I know it's open source, which is supposed to be the holy grail, can anyone elaborate on this?

2nd rant: Evo has a bunch of amazing features, but every phone is eventually overshadowed. Does it seem like this is going to happen even sooner with the Evo? I mean, rumors about the iPhone HD and HTC Incredible are all around. The new iPhone will apparently have an even better screen than the Evo and match it's front-facing camera. Believe me, I hate iPhones with a passion, but I secretly really wanna be able to put my iPhone loving friends in their place. And as for the Incredible, 1.5Ghz? Seriously?? Ugh.
