To be honest, I think I totally will.
I've been thinking about getting a new 3DS because I've had so much use out of my launch model, a LOT of use.
The serial code sticker has come off like any well used DS, the d-pad is flaking, the face buttons have hairline cracks, but more than anything, the touch-screen has become inaccurate and cannot be calibrated. For someone who loves Colors 3D this is heartbreaking.
Why I want a 3DS XL instead of another 3DS? Those larger screens look fantastic, and the drawing potential for apps like Colors 3D or Swapnote, and if it should ever be, a new Flipnote, oh BOY.
I'd keep the old 3DS for the oodles of streetpass hits I'd automatically get from each system together, coincidentally fabulous for Kid Icarus weapon fusion though I'm about done with that game now. But then, also for playing Kid Icarus because I imagine that game would be better suited to the regular 3DS somehow. That, and I suspect Kid Icarus is why my touch-screen is so inaccurate now, Sakurai has a knack for making handheld games that wreck havoc on a touch-screen, Meteos much?
