Is it not true that most of the widescreens are less costly than the non-widescreen ones atleast compared to the better models?There must be some distinction or else they will all make it widescreen or non-widescreen Shall do some search for the differences
Major disadvantage with widescreens is that not all games support them. Plus the additional benifit of using a 4:3 screen is the screen size eg. a 19" 4:3 appears much larger than a 20" wide. The 20" wide screen has the screen height of a 17" and the width just stretched out a bit.
Wides are great if your into DVD and working with multiple docs.
