I think it's more critical than just having less IE users in that space... The thing is, 1.6% of total traffic does not equal 1.6% browser usage.
If all your IE visitors are seeing is a landing page and a message saying "sorry, we're too lazy to support for your browser", then of course they'll turn around and never come back. If they were to let IE users through, that number would most likely jump up - significantly.
I know a couple of hardcore IT guys and programmers that are really happy with IE9, and hate Firefox and Chrome with a passion. It happens!
