Yes, DVI was popular there for a while, and there are an assortment of others, but HDMI seems to have outpaced DVI in my encounters (and the others are quite niche: some Mac, Intel, etc...). DVI is still attractive, but things are shipping without it in favor of HDMI (in my experiences), and that only further helps extend VGA's lifespan. People already have VGA cables, and their only "upgrade" path to digital is often HDMI, so VGA remains the lesser of evils based on price and personal lifestyle/ethics.
