This was both more and less interesting than I thought it was gonna be. On the one hand, I knew the answer to all of the cool graphical tricks was basically "more power!" On the other hand, I didn't know about the whole bitmapping vs. tiles. I really hope now, he goes back in time and talks about older systems. It'd be really interesting to see compare and contrasts between contemporaries like the Atari 7800, Nintendo NES, and Sega Master System or more obscure systems like the Neo Geo Pocket.
Related aside. The GBA is hands down, and probably will forever be, my favorite system (PS2 is a close second). It's the only system I got the year it came out, has some of my all time favorite games, and was just a simple, pure, gaming experience. I loved that thing.
