The Picade is a great little device that pretty much anyone can put together with nothing but a screwdriver.
It does, however, have a few shortcomings and room for improvements.
The most obvious shortcoming is the 8 inch screen shipped with the Picade. It's good, but it's only 8 inches. The cabinet is designed to take a 12.1 inch screen with a 4:3 aspect ratio but such screens are hard to come by these days.
