If you’re going to put in a video/out jack, why not have video/in too. Of course that opens it up for the no s-video and component complaints.
A TV tuner? Problem is that TV needs an antenna and the best possible internal would be a loop around the screen. (Excuse me, could we exchange seats, I nead to turn my PC) You’d still need an external ant. connector. Pretty expensive proposition just to make the TR a TV.
A bluetooth tv tuner would be cool, but I don’t know if BT has the bandwidth.
I’d like to see at least one recessed USB port so that dongles or cables don’t stick out so far. Even better might be an easily accessable USB compartment so small devices could be semi-permanently installed.
All-in-all, faster, lighter and more battery would be all it would take for me to upgrade.
