It seems that the 3DS is more generous in this regard. CNet quote: "Having used both devices, we reckon the 3DS is more generous when it comes to that sweet spot. You're not to going to fit more than one person around the console enjoying the 3D effect, but you can tilt the 3DS a good inch or so to the left or right without breaking the spell. The Optimus 3D's sweet spot is very tight, and moving your head (or the phone) just a little will turn the 3D image into a blurry mess." After playing with the 3DS myself a couple weeks ago, I found that it was easy to adjust to the 3D, and there was about a leeway of about 5cm of moving the 3DS around where the 3D effect stuck which was better than I expected.
