>The laptop doesn't fit on my desk. I got the docking station to be able to use the laptop at home.
FWIW, I also don't have a very big disk. The laptop thus sits on a stand that also puts the screen at a more ergonomic level. Not sure that would work as well with a bigger form factor than the 13" I have now ... but those aren't really fit to be called "lap" top anyway, as far as I'm concerned ;)
The cheapest and probably easiest way to implement the kind of HID switch you're looking for would be to use a VNC client on the computer with the biggest/nicest screen. You could probably make a USB switch yourself (switching just the 2 signal wire, supplying power from an external supply) but as soon as you switch to a different device the previous device will still see a USB disconnect. If that causes it to lose settings it will a priori continue to do so. Preventing that would require the switch to make every connected computer think that the keyboard and mouse are connected even if in reality they're connected to only a single computer. I'd be surprised if such a device existed, TBH.
