thanks for the reply..
i did have a look on ebay and there way plenty of these ones on there.
but when you view the sellers details they are anywhere other then the uk.
atleast the link you posted above, is for amazon.
didn't think to look on their..
i was thinking on paying the extra to get a usb3.0 version.
but read that some older usb2.0 devices struggle when connected.
so i think its safer to stay with a usb2.0 version switch
You could always try software I used to use Synergy with some sucess. Install it on both PCs configure it and then you can share KB and Mouse easily.
I cant remember if there was a freeware version.
The other alternative, if you use Logitech stuff, is thier Flow software, again just works.
