I head that regular N3DS have larger screen that the old 3DS, but smaller than 3DSXL, is it true? The old one is too small while XL is too big to fit into my pocket, so if this true I might changed back to regular size.
Yes the regular N3DS has slightly larger screens than the OG 3DS. Battery life a little better too.
OG: 3.53"
N3DS: 3.88"
XL/NXL: 4.88"
