Nice lil review. I like how you label the short controller cords and necessary tap as minor annoyances rather than the oft heard "omg-this-is-why-it-failed!" hysteria.
One note: first you say the PCE's library is 650 strong and later that it's 850. The latter is closest to the truth, but it's a hard number to nail down, depending on if you include LA games, homebrew, Games Express titles, etc.
