Hi guys
I bought this switchable USB hub thingy at the car boot sale this morning. To be honest I don't know why I bought it, I don't have any particular use for it, it just looked kinda.... cool... and I had 5 euros lying around in my pocket.
Now I don't have 5 euros - I have this thing instead lol

It has 7 individually switchable USB sockets and an external PSU connector
Somehow I think this must be useful around the workshop but I have no clear idea why it would be lol.
Any ideas (good or otherwise) what it would be really useful for?
