i see that opera, safari,chrome and all the rest are very flat. ok firefox is climbing a few points and ie has dropped a few ok so? not like it went from 70% to 10% ... and not like firefox has "crossed over" ... now if that trend keeps up perhaps next year
they might have a meeting point.
They would cross over in 2012. IE would still have 12% in 2018 (what's with that date anyways?). Firefox wouldn't pass IE's current number till 2019.
Sorry OP, you're going to be stuck supporting IE for a while.
