Froyo added auto-updates that work as jellicle described (you select it as an option per-app from inside the market app and it'll auto-update those apps that publish new versions whose permissions haven't changed). It is true that by default you still get notifications for each app update, but this can be disabled (go to the settings in the Market app, set the notifications setting to 'Do not notify me'). While technically this isn't quite the same as Chrome because the user has to disable notifications manually (and the notification option isn't a per app option, but rather for all apps), I think the system in place on Android strikes the right balance for a mobile device.
