Rom Manager is awesome.. There is no reason not to use it now. It is already faaar superior to anything else and I only see it getting better as more people jump on.
The thing I am most excited for is when it will be the standard way to customize your custom roms. Did anyone try installing Ultimate Droid with Rom Manager? It was so ****in slick! Now I have never used a BlackDroid Rom and never will but that was one thing that he got right.. One day I just clicked the spot to download for the hell of it and it brought up menu after menu of how to customize your droid. First a list of Kernels to choose from. Then a list of Launchers. Then a list of Themes to apply etc etc. There couldn't be a more painless way to do it than Rom Manager...
Since Pete is moving exclusively to Rom Manager, I'm hoping that these options in RM are the "goodies" he is talking about. I would love to just hit a check box for glass theme, chevy lv kernel, and helix2 launcher and get the perfect setup on just one boot.
ROM MANAGER FTW!
