Oh there's more

They also say that their Macs are stable, fast, secure and fun. Is there someone suing for those things too?

And let's not forget Microsoft, who says that Vista has innovations.

Polishing a turd

I find it hard to believe any "professional" photographer would trust in a laptop screen for photo work, but I think Apple was just caught trying to polish a turd. Many LCDs cannot display the full 24-bit color range (8-bits-per-channel) because of the (often cheaper) technology used in them. However, Apple, rather than simply letting the LCD display the 16 million colors to its hardware-limited abilities, chose to implement dithering to improve the apparent visual quality of the display. It might also save battery life as well, since they only need to use 16-bit colors. This is much like web browsers would do on color-limited screens of the olden days. Only someone with a very discerning eye--like a photographer--would actually notice this.

Apple should take down the claim, or simply show its users the limitations of its hardware.

6 vs. 8 bit.

Isn't this an argument about 6 vs 8 bit panels? When Apple said "Millions of colors" it implied 8-bit panels, yet they were actually only 6-bit?
2^18 (6*3) = 262144
2^24 (8*3) = 16.7 million.
Quite a big difference, and the two men were photographers--I think that gives a little credence to the fact that they expected the colors that were advertised.

I think the claim has a little more merit than you're suggesting.
