Ok, I have looked at many laptop screens, PC and Mac, and I think that the 17" Powerbook LCD looks stunning. However, I am confused by a few things. Can someone please explain what some of these resolution numbers mean exactly? The 17" PB has a max resolution of 1440x900 and is capable of displaying millions of colors according to its specs. How does this compare to say a Compaq or Dell that is SXGA+ at 1400x1050 or UXGA at 1600x1200 or greater and displays 16.6 million colors (24-bit)? To me, the PB screen looks better, but I just want to know what these numbers mean. Is the PB also 24-bit 16.7 million colors? How do you calculate dpi? What do others think of the PB display compared to the best PC laptop displays? Sorry for such a long post, I just want to make sure I am getting an excellent quality product if I am going to switch to Apple (I have always used PC's). Thanks in advance for answers to these questions.
