FWIW, the latest pimame includes mame4all. The pimame thing is just a customized raspbian image. I'm using that on my arcade setup.
I'm also using bunches of pi's to run my own cable tv setup. I run openelec on them with composite out, feeding into agile modulators that put each pi onto it's own cable tv channel. Each pi runs a playlist (on shuffle/repeat all) off of my iTunes library. So it's basically ye olde cable tv, but you control the content.
They're versatile devices to be sure. Their greatest value is all the software support. Technically speaking, there are better, more capable devices out there, like the Beaglebone Black. Unfortunately, they lack the software support the pi has. The pi has had a few years to refine the software stack, so who knows. Maybe the other devices will improve their software support over time.
