What are the advantages of creating my gamer card on Xbox.com before using Xbox 360?
The biggest advantage is that you can use your PC keyboard to enter all your information. If you create your gamer card using your Xbox 360 console, you’ll have to enter your info using your Xbox 360 controller and the virtual keyboard in the Xbox Dashboard. (You can also plug a USB keyboard into a controller port on the Xbox 360 console.) It’ll be a lot faster at Xbox.com, plus you’ll be able to get the latest scoop on upcoming games, participate in the Xbox forums, and view your friends and achievements on the site.
