As Apple continues to make all of its devices and services increasingly tied together, I'm thinking of bagging GMail and Google Calendars and going whole-hog Apple. (In addition, I'm growing increasingly distrustful of Google's "we'll give it to you free if you let us mine your data to sell ads" business model. Anyway, a couple of quick questions:  My Apple ID is my GMail address. I have one iCloud address associated with with account. I also have a second iCloud (@me) account that was created at some point. So in iCloud preferences on my Mac, both iCloud accounts show up. I'd like to use my @me iCloud account and get rid of the other which is my current Apple ID. Is this possible?  Are @mac.com, @me.com, and @icloud.com all equivalent/aliases?  I currently have 3 GMail addresses (personal, e-commerce, and forums). Can I get additional @icloud.com addresses or does Apple use "aliases" that are the equivelnet of individual accounts? Thanks!
