Many stores are already switching to cash registers with displays for the customer, at least in the Netherlands, so things like this could easily be integrated into existing POS platforms.

This seems like a great solution for smaller stores, but larger stores or chains that use custom POS platforms would benefit a lot from a standardized 'POS API' (as opposed to the usual Bitcoin API) that also allows for communication with a remote Bitcoin client (which will be the case in a store with multiple payment terminals/counters, where everything has to be handled by one central 'cash register server'), and that can be used without a GUI frontend - effectively making it very easy to implement Bitcoin into an existing POS solution without any knowledge about the underlying system.

Also, a small shop doesn't need a pc nor a laptop. Smartphones with dual core are sold today. You don't even need dual-core for this. A small screen and a smartphone is something any business can afford today. Two years from now this can easily and cheaply be mainstream.

I would say, though, that it'd be rather strange to see a smartphone mounted onto a counter, displaying a QR code

Actually, you could even get a cheap Android tablet or ebook reader (the latter will work better) from some random Chinese store, and run a simple application on it that will wirelessly connect to your 'payment server', and show the appropriate QR code and payment information. You can get a low-spec Android tablet for <$100 from China, and some simple ebook readers with epaper sell for about $100-$150 (with WiFi capability).
