Javascript event handling (all browsers except ie7)

Now that IE9 supports addEventListener and IE7's market share is diminishing (goodle analytics tell me that ie7 and older is at 14% and loses 2% per month).

If we can support ie8 (@31%) we can forever forget attachEvent.
That mean we support all current browsers but not ie7 and older.
