I've had the same discussion with myself. But my purchase is for my 8yr daughter.
Only reason I'm considering 2DS is its cheaper and less likely to be damaged... but I don't think she'll damage it in reality, the 3DSXL is a more full featured machine as at least she has the choice with 3D, and there are better color options. So considering I can likely find one for around $120~$130 used... I'm still leaning 3DSXL.
I'm waiting for E3 to see if there is a redesign with better battery life or something before I decide.
