The customer is always right.
Personally, I don't want Games Centre, I never asked for it and if I don't want it, I am well within my rights to delete the icon rather than to have to move the icon to the last screen, out of the way. With Microsoft Windows 98, I can delete most stuff I don't want, but with Apple iPad, I can't seems to delete anything I don't want.
I don't like the idea of too many replies saying: "Just log-on." Boaterbob is right, after logging on, THEN what??
Beside, the original poster, Techician is right, what if I don't care how I rank against others, all I want to do is to play Flight Control HD just for a bit of fun and to kill time, not to compare against others, therefore what is the point of having to log on?
