not all businesses = big corporations. In fact the vast majority are not.

Small Business isn't the driving factor of extended XP support though, large enterprise is.

Small Businesses would be unwise to further invest in sustaining XP and if Small Businesses want to leverage modern web applications i'm pretty sure they have already upgraded to Vista or 7 to take advantage thereof.
