Having 2 or 3 PDS slots would be interesting for video, networking, and maybe a spigot card for capture.

I kind of wonder why they didn't make zero footprint HD/CDROM expansion for the LC line like they did for the compacts. Somebody did make cool external HD bays for the 800/840av/8500/9500 series that looked just like an 800 case that got kneecapped, wish I bid on it back then.
