Call me crazy, but I don't really get what the point of this strange dual-monitor contraption is. A 22-inch widescreen LCD monitor with a 7-inch LCD attached to the side for some unknown reason, it supposedly gives you more space to work.
But come on, if you're going to have a dual-monitor setup, why not just go all out? You need more than a 7-inch screen to get all the benefits of having two monitors, so you might as well suck it up and get two 22-inchers. Sure, the $550 price is more reasonable than most similar setups, but in the end, you get what you pay for.
