I'm waiting for the 2DSXL where both screens are the same XL size and they go back to stereo. I don't mind the looks of the flat wedge/cake shape though it does make it permanently larger and exposes the 2 screens to inevitable scratching. I usually buy cases for my gear though.

And even scarier, how many hours of video on YouTube are WORTH watching?

While it may be unlikely that you will catch fire while swimming, you should always be prepared to catch fire while water-skiing. As proof, the latest ICD-10 codes are ready for just such an event:

V9107XA = "Burn due to water-skis on fire, initial encounter"

I kid you not. http://graphicsweb.wsj.com/documents/MEDICALCODES0911/#term=Water-skis

Additionally, this problem has already been solved for a group of people more likely to truly "need" it, and who do use it. You can find it at http://roadid.com/
