For once I agree with Pachter!
It doesn't really change my opinion of him but it's nice I agree with him. There are silly names like iPod, Wii, and Kinect that roll off the tongue and/or just makes sense.
iPod -- completely made up word but it uses apple i branding (even though it wasn't that large yet) and it sounded good.
Wii -- Another made up word and it sounds a bit vulgar but it is memorable and it rolls of the tongue well. There's also that whole Wii would like to play thing.
Kinect -- Oh I see it's all about movement and that connection being the controller, it makes perfect sense.
Vita -- Vita, vita, vita. It really doesn't sound very good, it doesn't roll off the tongue at all, and it really doesn't have any connection to anything.
