Love my Pro8 docking station ! Have Dell Venue Pro 8 tablet, just upgraded to Win10, and love that it still works with the Pro* docking station.
I also have a 3900 that I plan on using with a HP Slate 7, and giving to a friend who is without a PC and in a tough spot financially, and has a kid in school.
Can’t wait to see what you come out with to support Win10 Mobile Continuum
Thank you !
