I'm sorry, that was unclear.

What I intended by the word was simply that from an aggregate perspective, the optimal solution would be everyone, as matt said, using a good browser instead, which would require minimal effort by users, and make the time investment from developers unnecessary.

Still, I've edited to the more neutral spent.

ETA: I suppose if you wanted to put a dollar value to "time wasted", you would have to subtract off the dollar value of the time it would take for each present-day IE user to download Firefox, Safari, Opera, Chrome, etc, import any bookmarks, and become familiar with its workings up to the level at which they were previously proficient in IE. This amount is non-negligible, and I was wrong to overlook it, but I strongly doubt that it is of the same order as the developer-time spent.
