I will be able to upgrade my phone in a few months, but I don’t understand what these things exactly are. I have an orginal Moto Droid and I think it came with vanilla Andriod but I hear people complaining about Motoblur. Are these things nothing more than graphical UI’s that companies have installed over top of Android? I am using ADW launcher, If I get a phone with one of these UI’s will I still be able to use a launcher? If I decide to customize the interface a bit will these UI's allow my own customizations?
