You've never had Windows insist on installing updates at an inconvenient time? Come on! You're obviously not using Windows that much.

Also, it's not just Windows that does this. Every HP thing (the PC, their printers, accessories, etc) seems to require a bazillion background services and one gigantic background app that just loves to pop up and interrupt everything you're doing at the worst times. Multiply that by any number of other devices with proprietary management daemons running in the background, managing their own updates (because even to this day Windows doesn't have a universal package manager that keeps all software up to date).

This is how it's going to go:

1. You bring your shiny new Lenovo portable game console with you to the airport so you can game while waiting to board and during the flight.
2. You wake it from sleep (because nobody is actually going to fully power the thing down and wait for the lengthy Windows boot/login process every time they want to use it).
3. Since it's been asleep for a while it'll immediately check for updates. If there's no Internet you're golden! The moment you connect it though...
4. Updates will be downloaded in the background while you're gaming. Not a big deal on it's own but as soon as they're done they will be auto-installed and Windows will ask you to reboot... Because it can't actually apply updates without rebooting 95% of the time (depends on what was updated).
5. You'll notice that your device isn't running quite as well as it used to or something isn't working quite right (e.g. wifi keeps disconnecting because one of the updates applied new firmware but the driver update won't apply until you reboot) and everyone knows that a quick fix for that is to reboot.
6. You sit there in the airport waiting for a ton of windows updates to apply on boot. Then when it's done it might ask you to reboot again because while those updates were applying it applied more (because many updates have to be applied in a certain order).
7. There goes 10-20% of your battery life and probably 15 minutes of your life you'll never get back.

It's the Windows way!
