There are a few games which are made specifically for tablets, but I dunno if they're only the 10" variety or if they also have 7" variations. Does anything like that exist for 10" tablets? On the subject of using a tablet like a book, can anybody recommend a good case for such a tablet? I have a friend who has a 7" galaxy tab and he has this holder which is shaped like a book that makes holding the thing, and reading with it, much more comfortable. Got my Galaxy tab 10.1 largely for reading back issues of gamepro and EGM from retromags, and yes, they make awesome readers. That's one of the reasons I got mine and it worked great. I fully support a tablet for reading comics. A few games do offer HD versions or support, but I'd say most don't. I have a 10" tablet, and I have no problems.
Most games are just blown up, but it doesn't really bother me. Do games scale up to 7" well or do they look like you've blown a thumbnail picture up? I hadn't even thought much about gaming on one because I have my phone and 3DS.
BETRAYAL AT KRONDOR FOR SCUMMVM ANDROID
I've been considering picking up a cheap 7" android tablet for comic reading. Maybe a bit unwieldy for a phone, but it's great for a tablet with a stand. Numerous games support the keypad, but most don't advertise it, so ymmv.
The ScummVM wiki contains a comprehensive list of all SCI games. And not all Sierra games were a variant of SCI just the adventure games. Dynamix did not use the SCI engine in its games, including Betrayal at Krondor. This makes a bunch of games feel a lot better - it's way more awesome to play Sonic CD on a tablet with a wiimote than with the touch screen controls. Every RPG lover remembers this awesome game from 1993. I'm thinking that dynamix was folded into sierra, and that at that times all sierra games were a variant of SCI. Second, and more relevant to anyone with a tablet or phone without a keyboard, is that you can very easily connect a wiimote to your android device via bluetooth (there are several free apps on the app market which will do this for you) and map keyboard presses to various buttons on a wiimote, nunchuck, and even classic controller. It's called the game gripper and it's an awesome accessory: The reason this is so cool is two fold - first, there exists slap-on controllers for just about every keypad made.
Sonic CD, for example, will map the d-pad to wasd, and jump to the back key.

On the subject of controls for android games - since android natively supports hardware keypads, a large number of games have hidden keypad support.
