I would not bother with a redirect and I would not use IE to view it. If I hit a flash site that takes more than 20 seconds to show anything beyond the loading loading loading, I say forget it.

I'd personally get a different template mac snob or not. I have had to make changes to make things compatible for IE, which is not the most compliant browser out there. Enough people use it that I am not going to lose traffic over it.

Was it a free template? Why choose one that says it isn't compatible with a browser that 21% of people use? So, basically a quarter. While safari only has an 8% share. Though IE is still the leader with 66%

Just a thought. I have said here before that websites should be easy to use, load as fast as possible and if you are selling something, don't make it hard to buy!
