Um, there's a little thing called screen real estate which means if you do a split screen, you'll be squished into a tiny corner or half of a screen which is ALREADY small considering we're talking about a portable. So if you're saying that we should just stick to the regular GBA and split the screen... *no.* If you're saying they should just get one big screen, well I dunno. Maybe, maybe not. People are hypothesizing one ARM processor controls one screen, so imagine what advantages this will have over one big screen.
I'm still disappointed though. Mainly for this whole "third pillar" thing and whether or not this is a smart business move (dammit I actually own stock. I'm losing $. my own fault for buying though.)
