You're wasting your time if you worry about legacy browser support. Period. For every legacy browser out there--a number which only grows in spurts when a browser becomes "legacy"--there are maybe a 1,000(,000) shiny new browsers being shipped daily. Which do you care about? A stagnant legacy count, or a growing demand of new, mostly compatible, mostly upgradable browsers?
