Picked up a red 3DS XL with NSMB2 from Gamestop. Nobody else in the store was there to buy the system, which was just like last year when I bought the original 3DS from the same location. The told me that I would not be able to get $100 for a 3DS if I brought one in later; that promotion is only good at the time of the XL purchase.
My XL didn't have any dead pixels or other defects. The system doesn't feel that much heavier than the original 3DS and the casing is a darker, more metallic red than some of the photos that have been posted. of it.
The system transfer wasn't too bad- I just copied the 3DS 2G SD card contents to the XL's 4GB SD card, put the 4GB card into the 3DS, then started the transfer process. Being prompted multiple times with what was essentially "Are you sure you want to transfer? Are you really sure? REALLY REALLY SURE?" was kind of annoying, but whatever-- it's a one time thing.
Now onto what's important:
-The screens really are THAT much bigger. Huge, huge difference.
-Virtual Console games look a lot better on the XL screen (when launched with start held).
-Regular 3DS games vary. SSF4 3D Edition looks awful; it's like playing the iPhone version now. Tekken 3D also didn't look that much better and the 2D artwork appeared very grainy. Although a little grainier, I thought RE The Mercenaries looked good. Super Mario 3D Land looked great.
-The original 3DS hurt my left hand after 10-15 minutes of use on a lot of games. I have only found that SSF4 continues to cramp my hand, and even then it's not as bad as it was on the 3DS.
-The Select/Home/Start buttons are MUCH better.
-The speaker quality is still mediocre and the volume is too low. I thought the same about the original 3DS.
-The hinge feels sturdier and the 3D on/off switch has been improved. You can now "lock" 3D in an off position.
Overall the XL feels like a minor upgrade. I bought it mainly for comfort-related issues with the original 3DS and have had mixed results. The larger screens are nice for older games, but 3DS games don't look as crisp and sharp as they did on the original 3DS. I don't feel as if I wasted my money on the XL, but if I had the opportunity to try it before buying it, I'm not sure if I would have purchased one. No question that it has been massively-overhyped.
