The frustrating thing is that machine only has 2 USB ports, rather than 4. So one port for power and another for a single wired accessory. I guess buying a dongle isn't a huge deal, but kind of frustrating that you'd have to spend more money for what I would expect to be included functionality for a "pro" machine.

So I suppose in theory if you wanted something new but without breaking your workflow, you could just go for that one.
