I am an Android virgin and only use my @gmail.com email address for YouTube, Latitude etc. I am considering a move to Android (SHOCK HORROR) and if I do I will move my email accounts which are on my own domain to Google also.
I have ended up with 2 AppleIDs, a me.com one and one using my own domain email address and Apple awesomely won't provide a way to combine them or move purchases from one to the other. I don't want this to happen again.
So, my question, does Android on entering an email address on setup/registration populate that through all the settings/apps on the phone? Or can I quite happily continue using my @gmail.com address for some google services and my own domain email address for other ones?
