Real-y, define free. The wireless functionality has finally caught my attention. The wavebirds are great. Still I doubt we'll get that much range on them but still nice not to be corded (20 ft is nice). I hope DS links wirelessly with the GCN 2, I hate GCN-GBA connectors!
Also I've been out of the DS loop, how concrete is the stylus? (I can see myself or my siblings losing that already)
