According to my stats, 5.77% of vists to the UMPCPortal are from people with screen sizes of 1024×600, 800×480 or 800×600. Those screen sizes are almost exclusive to the ultra mobile PC (MID, pro-mobile, netbook) class of devices so its got be close to a 1:1 relationship.
I wonder if that same 5.77% statistic will appear if I put a poll here.
Look at the growth of the 1024×600 screens. Its not just cross-sector growth either. The 800×480 graph isn’t going anywhere!
