The Vivitar V5119 has one of the smaller display diagonals (only 1.8 inches) amongst low megapixel digital cameras of this age. The display diagonals of low megapixel digital cameras that came out around the same time as this digital camera range from 1" to 3.5", and the average display diagonal is 2.6".
Alternative 1.8" screen cameras currently available that you might want to look at include the Nikon Coolpix 8800 which has better reviews.
If you would prefer a larger display diagonal then you might want to consider the Canon EOS 400D - Rebel XTi (2.5") which also has a higher rating.
