I have a 32 inch 1080p Sony Bravia - I love it - the picture is outstanding with no flashlighting, no clouding, inky blacks, and matte black screen. I originally bought a 40 inch and swapped it for a 32, since I was playing close to the screen while gaming.
Recently got new furniture in my small apartment and now I spend more time watching TV from the kitchen table, so it seems too small. Kinda wishing I kept the 40 incher I originally bought 3-4 years back, because the new LED TVs have screen uniformity problems, not enough HDMI inputs, terrible built in speakers, no 120 hz options on lower priced models, or terrible gaming lag (a big deal for me). I love how my current 32 handles 24 fps content.
My other issue with looking for a TV is that while the bezels are shrinking with no front spacing speakers, so do the speakers which sounds worse and worse. I've got a spherex 5.1 channel setup that is great, but the center speaker is pretty tall. A new 40 inch TV would look great, but the TV would be partially blocked from view by the large center speaker.
I am super close to buying a closeout priced 40 inch Sony KDL40EX640, but the horror stories of screen uniformity are scaring me off!
As for the chart, I game about 5 feet away (hence the 32 is darn near perfect, so I don't make myself sick), but my kitchen table is about 10 feet away, Argh, I'm going nuts trying to find a sweet spot screen that matches the gorgeous backlit LCD TV I currently have. It seems like all the bells and whistles (like local dimming) are going into higher end large models that start at 46 inches.
