I'm just going to add a few things:
These screens are made for the climate and abuse of a car. Mine just survived a winter with temps down to almost -40 degrees with no ill effects whatsoever.
Yes, you can achieve a lot of the functionality with a in-dash GPS/Multimedia unit, but those cost as much (or more) than this setup, and it does not do the same thing. Find me a DVD/Nav unit that you can use to tune the Tweecer with.
Yes, watching movies on it while driving is ********, but that's hardly unique to a computer, you can do that with any sort of DVD player. Using it for music is no different than using a normal HU. It also functions as a hands-free unit for cell-phones, so it can even make you less distracted while driving, if you're someone who talks while driving. On top of all that, since it's a computer, it's fairly trivial to set up voice recognition commands, so he doesn't have to actually look away or touch it at all.
From experience, he will not be tuning while driving. A touchscreen gives far too little resolution to read and select the values in CalEdit. To tune, he will need to hook up a mouse and keyboard, probably wireless.
Lastly, that looks a little rough, but he said he's not done yet. Mine looks a lot nicer than some drop-in unit because it's nicely moulded into the dash, not slapped in there with some adapter kit. It's not even that much work, and it's nice having something custom made (by yourself) than something you just bought off a shelf.
