Ben,
I'm a little late getting back to you but your i7 2670QM notebook computer would be excellent. Because
Dragon Medical Practice Edition utilizes 2 cores, when possible, it's better to purchase a quad core over a dual core and this computer is a fast quad core with plenty of RAM.
The only real disadvantage of a notebook computer is a smaller screen and smaller internal parts which means they're easier to break and easier to lose. I recommend opting for the docking bay because it'll give you more ports and there will be fewer items to unplug when you leave. I also have a slight preference for solid-state drives but this is by no means critical. Dgrauman?s additionally made some excellent points.
