VGA - Video Graphic Array
QVGA - Quarter Video Graphic Array

VGA -
The term Video Graphics Array (VGA) refers specifically to the display hardware, through its widespread adoption has also come to mean either an analog computer display standard, the 15-pin D-subminiature VGA connector or the 640×480 resolution itself. While this resolution has been superseded in the personal computer market, it is becoming a popular resolution on mobile devices.

VGA was the last graphical standard introduced by IBM that the majority of PC clone manufacturers conformed to, making it today (as of 2009) the lowest common denominator that all PC graphics hardware supports, before a device-specific driver is loaded into the computer. For example, the Microsoft Windows splash screen appears while the machine is still operating in VGA mode, which is the reason that this screen always appears in reduced resolution and color depth.


QVGA -
The name QVGA ( Quarter VGA ) is derived from the fact that it offers 1/4 of the 640 × 480 maximum resolution of the original IBM VGA display technology, which became a de facto industry standard in the late 1980s. QVGA is not a standard mode offered by the VGA BIOS, even though VGA and compatible chipsets support a QVGA-sized Mode X. The term refers only to the display's resolution and thus the abbreviated term QVGA or Quarter VGA is more appropriate to use.

QVGA is a popular term for a computer display with 320 × 240 resolution. QVGA displays are most often seen in mobile phones, PDAs and some handheld game consoles. Often the displays are in a “portrait” alignment (as opposed to “landscape”) and are referred to as 240 × 320 as the displays are taller than they are wide.

I would prefer VGA over QVGA simply due to the several advantages of VGA (over QVGA).

Advantages of VGA (over QVGA) -

VGA offers 4 times information with the same quality than QVGA to view on the screen

Also, quality improve tremendously with same amount of information on screen (because now you have 4 pixel to display something whereas before you only get one pixel to display it)

With respect to size -
You can view msot of a web pages with minimal scrolling.
you can view pictures witt minimal scrolling
you can view larger portion of a page of text with minimal scrolling.
you can view excel sheets wiht minmal scrolling.

With respect to quality
powerpoint slides etc can be view now with clarity. Small texts will be clearly defined. Videos will be clearer, more detailed. You may actually see eyeball from eye lids instead of 5 pixels of varying degree of gray.

In VGA, the photography is particularly excellent, and shows the details that YouTube's craptastic quality cannot. Worth a look! I adore VGA screens, but they never seem come on the devices that I like - the small, thin, light devices. Hopefully as things continue to evolve we'll see more VGA screens...
