Fuel to the home vs arcade debate, not many of us have proper MAME setups or even JAMMA quality console sticks at home, let alone dedicated arcade machines. I don't know what 5.1 surround sound and a comfortable sofa is going to get you because I've never seen an arcade game that could be effectively played that way.
That's because I forgot to mention one of these:

How many adults will cruise to the nearest arcade with a couple of rolls of quarters and a few friends? Versus how many adults will pick up a wiimote or a Guitar Hero controller.
