nathan:Wade: As far as charging and USB hub this adaptor is the one that people have reported as working fine with the HP Stream

I would only sink decent money into a windows tablet if it had a minimum of USB3 and full HD, a $500 8" surface 3 would be ideal imo :P
Is there another link, that is 404
Noted that you would like a Surface Mini :)
My store (tap that tablets) will have some charging hubs in soon. Probably monday (as soon as they clear customs). Sorry for the plug, but seemed like it might be helpful, seems like a lot of people here are looking for them.
