Re: Nice, but?
"BT rather than reliable USB for keyboard and mouse is a mistake?"
Ties up a USB port, and I have to say, never had a problem with my BT keyboard with tablets in the past. Beens using them for I guess, close on a decade.
Just bear in mind the keyboard, mouse and Pi are only a few cm apart, where as on a pc it could be almost a metre, through a desk and around the back.
