I bought the new 2DS XL and here are my first impressions:
-It's lighter(it weighs exactly the same as the flat 2DS)and more balanced than the 3DS XL.It doesn't feel top heavy like the 3DS XL.
-I agree with KnightsSorrow...images on the screen are a bit sharper and the colors are more vibrant than the 3DS XL.
-Worst.Stylus.Ever.The stylus included is short and fat and uncomfortable to use.
-Build quality is good.It has a more utilitarian look than the 3DS XL but it doesn't look cheap like the flat 2DS.The bottom shell is a matte black and the top has a nice ribbed texture.
-I noticed that I can feel vibrations from the speakers in the bottom shell while I'm playing.
I need to play this machine a bit more to get a better feel for it.As far as I know,the white and orange version is available in the U.K.,Europe and Japan(and possibly Australia) but not in the States.
