Slightly off-topic but the new ad for IE made me laugh! Their strapline, Why settle for second best? implies they are the best... With a score of 32/100 on the Acid3 test, I will continue to use it for testing only.
IE is the "Quarter Pounder" of browsers. McDonald's sells more Quarter Pounders than any other burger, but that doesn't make it the best.
IE comes with every PC running Windows. I'll keep Firefox.
