Yes, obviously don't "press" on the screen, but if you find yourself putting your hand on it just to support the device, that's totally harmless.
With my CyBook, however, it lives in its case permanently, and I generally hold it just like I would a book, with the case hinged open like a book and holding the spine and the two edges. I did the same with my Sony Reader, and I'd imagine the same should be comfortable with the EZ Reader too.
