Wouldn't it be much clearer and much less confusing to use the actual pixel sizes? If that's too long, we can use the equally unambiguous decapixels: 6x4, 8x6, 10x7, 12x10, 14x10, 16x12, 19x14, etc. Now, I can tell EXACTLY how fine the pixels will be, instead of having to search for a glossary (which, by the way, the laptop manufacturers conveniently neglect to include in their brochures).
SUXGA just sux. Get rid of it.
