>>14562773The original 3DS is actually quite uncomfortable to use for extended periods, you will find your hands feeling cramped and the corners of the system digging into your palms, plus the d-pad awkwardly positioned leading to further discomfort.
That last point really matters because X/Y actually provides two means of movement, rollerskates on the circle pad and normal walking/running on the d-pad.
>>14562822That's actually true, the 60'' screen has a lower DPI, but then it's intended to be viewed from a further distance anyway.
Personally I find that even though the 3DS screen is the same size as the DSi screen, that higher resolution makes the screen feel too small, strange as it sounds.
