Sell the home computer: iOS5 will have smaller, over-the-air updates

Settings app displays a badge when
an over-the-air update is available.

Portable Apple devices will update over-the-air so you don't need to plug into the home computer.  iOS5 will be out shortly. Only the changes, not the whole blinking file will be sent, so it won't take too long. The Beta wireless version uses 133 MB while the previous plug-in version used 824 MB.
