Recently Dell introduced the largest tablet available to the consumer market, the XPS18. This tablet has a screen size of about 1'-6" diagonally [note that the iPad is a mere 9.7"]
It makes for a great markup tablet because it runs full-blown windows, which means you can install Bluebeam, or Design Review or any other Windows-based software for that matter. It's a "capacitive touch" display which means you can use your fingers or a capacitive pen (one of those squishy-ended numbers) and of course the on-screen keyboard. Not all applications support multi-touch yet but I know that the latest release of Bluebeam does.
