For the record, I hate IE with a passion. But look at it this way: If you purposefully ignore a segment of the market you open yourself up to attack. Better have that cost-benefit worked out, too much work probably isn't a good excuse at any scale that matters. If you're just playing around then fine, go for it. But if you're playing for keeps then be very careful with decisions like these.

You'll be on your high horse over there telling people to upgrade or gtfo, meanwhile I'll be over here making off with a very large chunk of your potential userbase and everybody they pull along.

That adds up, and if you're not careful it will add up to business failure. Ignore your potential users at your peril.
