Some people upthread were right; there did seem to be many instances of people talking over one another this episode.
I enjoyed the episode, though!
I'd have to say that there is nothing about the DSi that I find particularly compelling; but, it probably will give me occassion to buy a DS Lite once the price drops a bit. Like Crimm, I only have a DS fat. I haven't wanted to spend the money to upgrade yet, but I'm notoriously cheap.
Given that Nintendo was pleased with the sales of Sin & Punishment for the Wii, then I do have to wonder why they haven't chosen to release Earthbound. It's a baffling decision, really, since the series has had a somewhat vocal and dedicated fanbase. It's almost a cult.

I imagine that if Earthbound were released on the VC, many of them would probably buy the game (even though they've already played it) just on the hope that it would encourage Nintendo would finally release Mother 3 here. Just IMHO, though.
