Looking forward to the other half of this review. I'm still enjoying my Supaboy(audio issue and all), but I'm definitely interested in how the competition stacks up. Speaking of the Supaboy, couldn't you just get a 1/8" plug at radio shack or somewhere, without the cord, just the plug and put it in the A/V socket to use external controllers in portable mode? I haven't tried it, but seeing as the screen stays on even with the A/V cords plugged in, it seems like a viable option to me.
