5 games isn't really enough to cover the GB portfolio in its entirity. I'm glad you discussed why it survived when so many other systems failed though. I recall back in the early 90's I read an articale in Zillions (a Kids' spin-off of Consumer Reports) where they compared the Game Boy, Game Gear, Tubo Express and Lynx, and somehow came to the conclusion that Game Boy wasn't the one to buy (I guess they didn't figure in battery life).
I actually think the iPhone/Touch may be the true adversary to the DS, though I have yet to buy any games for mine.
Also I was thinking-maybe you guys could do a Wizard retrospective later this year for the 20th anniversary of that (then again, maybe I'm biased because I helped get it on DVD).
