Abandon Hope, All Ye (IE) Users

Interesting that when the BBC dares to carry a negative story about Microsoft, it immediately becomes the most-read and most-emailed - perhaps they should do it more often:

Users of the world's most common web browser have been advised to switch to another browser until a serious security flaw has been fixed.

Good advice, by why only until fixed: surely, the logical thing to do would be to abandon IE altogether, thus avoiding future problems too?
