I fly an Arrow with an Aspen in it sometimes. I can't stand the thing. Way too cluttered. Too much information in too small of a space. Too many buttons that you're unsure what they do. And, personally, I can't stand the way they look in a panel. That long, slender vertical install, with obligatory panel cut-out looks god awful. Even if you mount two G5's vertically, at least you can make a nice little gap between them to break it up a bit. Feng shui and all that, but seriously, two G5's just look nicer than that odd box of an Aspen. The G5's are intuitive, simpler, they just make sense.
