Given a choice, I'd pick the tablet experience for an old-school PC revival. Take it anywhere with you. Have it comfortablt positioned. Not be dependent on access to the TV. Have a very natural point-and-click interface.
Heck yeah, there's a lot of old school PC games that would be awesome on a tablet. Rogue, Cannon Fodder, Syndicate, Populous, Fallout, Ultima series (before they dropped stat based gameplay in favor of action based gameplay), etc...
Heck many of the early turn based RPGs would be fantastic on tablets. Pool of Radiance, Bard's Tale, Wizardry, etc.
Old strategy and sports games. Imagine the first few Maddens on tablet. Being able to just touch the receiver you wanted to throw to.
Agreed though on hardware limitations not being an issue for
most point/click adventures, but I had to throw that dig in.
Personally, I'd prefer the big screen and the couch with Kinect2 (better accuracy, less lag) or Move, but that's me.
Adventure game revival on tablets would certainly have me grinning from ear to ear. Even though there are some good ones that pop up now and then on PC, I still miss companies like Sierra (King's Quest, Space Quest, Leisure Suit Larry, etc.) and Lucas Arts (Grim Fandago, Maniac Island, Monkey Island, etc.).
And you can game on the big screen with a tablet easily enough. Well at least I can with my Windows Tablet. Although there's a bit of a disconnect between touching the screen of a tablet and watching your actions on a big screen.
Also wouldn't see mind trying to play many of the aforementioned games with Kinect.
Something like Dungeon Master by FTL or Eye of the Beholder by Westwood would be perfect for full body control. Especially the first as you had to choose runes to cast spells. You could actually pick up and throw things (both games). Attacks are easily emulated as they were basically just slash and shoot without any aiming requirements. And they had somewhat realtime combat with easy to kinecticize movement. Might and Magic RPG series by NWC would be right up that alley as well.
