Many Thanks



Answer
Well this answer could get very long if i try to describe both those technologies for you, so here;

Plasma: http://en.wikipedia.org/wiki/Plasma_display
LCD: http://en.wikipedia.org/wiki/LCD

Both types have their positive and negative sides but Plasma is the best in terms of picture quality! They have the highest contrast ratio's(2,000,000:1 dynamic; 40,000:1 native) and the fastest refresh rates(600hz)! They are perfect for the living room and watching fast motion content like sports, movies & gaming. I own a Panasonic 42" Plasma TV and i absolutely love it! Great TV!

LCD's also have great picture quality, but still not as good as Plasma...even with the new LED backlit LCD's! LCD's are best for rooms with lots of ambient light do to the fact that Plasma's can have screen glare!

PROS http://www.cnn.com/2005/TECH/internet/06/23/evolution.main/index.html
(CNN) -- In 1994, most people had to call the bank to check their balances. Or inquire in person, or wait for a paper statement to arrive in the mail. Baseball box scores were found in the newspaper. Weather forecasts came over the phone from the weather bureau, or on TV. Back then, most Americans still had to lick a stamp to send mail.

The World Wide Web has transformed the way people live, work and play. People can play travel agent and book all the elements of a vacation online. They can arrange for their bills to be paid automatically while they are gone. They can put a hold on mail delivery, find directions to tourist attractions and get a long-term weather forecast before they pack.

All kinds of information is available. People no longer have to consult medical practitioners to get an overview of what may be wrong with them. They can learn about medications and side effects. You can also get information about your pet and there are websites where an online vet technician will answer your questions right away.

There is access to the latest science information and journals. You can get the transcripts from Nova and other science TV programs.

You can get information for homework and tutorials on things that are important to you. For example, you can learn how to apply make-up or how to cook a recipe.

The Internet has created a global community. I can play chess with someone from Thailand and answer a Yahoo question for someone living in the Philippines. People can practice a foreign language on various forums.

CONS
Many of those online users are irked by spam -- unsolicited offers for everything from lower mortgage rates to pornography, pharmaceuticals and pitches to help a Nigerian launder millions of dollars.

Another e-mail problem is phishing, the fake e-mail that looks like it is from a legitimate source. The bogus e-mail is designed to get the reader to divulge personal information, often a credit card number.

Identity theft is perpetuated by obtaining online information about someone. That is a danger. Also, chat rooms have led to pedophiles having access to kids.

Another "con" is the amount of time kids spend playing games on the Internet instead of doing homework or getting exercise.
