Jason Dunn over at Pocket PC Thoughts found this great article on VGA vs QVGA screens on Mobil Yazilar Blog
The article has some fantastic screenshots of devices with VGA and QVGA screens. What most people don't realise is that the increase in pixels isn't just increased resolution but also clarity of the text and images.
You can see all the photos (much more than the one I've posted here) at the original article HERE
