Anybody using the new HP TouchSmart 600 Quad Core i7 machines hard-wired in their exam rooms with AC? Are they fast and accurate enough to navigate AC and/or correct DNS mistakes. I've used Touchscreen laptops wirelessly with some success, but want the network wired for speed and larger screen real estate for patient viewing. They're pricey but not out of the question. I'd plan to upgrade to i7 Pro. Any takers?
