I've got one of the plastic-backed Stratacoustics--it's a decent couch guitar and sounds, like you say, passable as an acoustic plugged in. I'd like to put a magnetic pickup into it but don't want to booger it up. The old solid body Teles with a regular neck pickup and a piezo bridge always intrigued me too.I've played the Strat Acoustasonic. Unplugged, it sounds about as good as Ronnie in the video. Which is to say, not very good IMO. Hey, it's a < 2" thick acoustic. BUT, plug it into an acoustic amp and smile. If has three pickups, five positions, and there are some nice plugged in acoustic sounds in there. In a blind test you could fool people.
The earlier version, the Stratosonic is a slightly different beast. It has an ovation body. Much better acoustic (unplugged) sound. Still not a Martin, sounds like a fiberglass ovation, but it's a usable sound and a passable acoustic for playing around or as a travel guitar. Not as nice as the Acoustasonic plugged in, but still nice.
I didn't get to play either of the Tele versions.
Ronnie's clip didn't make me want one of those guitars. Not sure what the point was.
Mick looks pretty comfortable with a guitar. I'd like to see more of his noodling.
