Hi,

I'm going to be buying a Macbook Pro after Macworld and I was wondering what are the differences between a LED and LCD screen? I am not sure if I want to get the 15" and take it with me, or get the 17" and use it as a desktop. I currently have a 13" Macbook, so I could use that while I'm in school.

I just want something that will allow me to play some games and will last me longer. I get my last fellowship payment this month and want to buy a new computer.
QUOTE Thanks

you are correct

Uliari - both screens are lcd (that is the type of screen) http://en.wikipedia.org/wiki/Lcd
The difference is that the new macbooks and macbook pros screens are now backlight by led's instead of some fluorescent tube thing. (someone please expand)
The backlight is what lights the screen up, and the screen is what displays the images.

Led's produce little to no heat, don't wear down over time, are more efficient, extend battery life, etc... http://www.macrumors.com/2007/06/05/...o-led-details/

Most LCD displays are backlit by what's called a CCFL (Cold Cathode Flourescent Lamp). Technology has improved to the point where LCD panels can now be backlit with LED. More and more laptops, desktop monitors and LCD TVs are now using LED technology. It's the wave of the future.
