LOL! Yeah, that must be what the 5200 engineers were thinking way back when..."the bigger we make this new 5200, the better it will be!" "We shall release the largest system of all time!!!!."
It really does make you wonder why the 5200 is so large. I bet it could have easily been 1/2 to 1/3 the size of what was released.
Hence the unreleased redesigned 5100 (aka 5200jr.).
