That's right. Now even consoles are getting upgrades & patches. If you are one of the lucky Xbox 360 owners, the next time you connect to the Xbox Live service, your console will download and install a software update for itself, which includes a variety of fixes:

Improvements to the Xbox Guide.
Option to retain your saved games when you delete a profile.
Increased accuracy of "last time played."
Network configuration improvements for Xbox LiveŽ members in the Netherlands.
More detailed messaging for unreadable disk or region errors.

Only the first of those really happens to affect gameplay all that much, though it's an interesting time we live in when a console, typically thought of as a pretty static, unchanging firmware-crafted device, is getting online updates. That does seem to be the trend future consoles are heading towards, and is likely to become even more prevelant.
