Why is IEx64 not the default for x64 Windows?

I don't think I've seen any answers to this question, but I'm curious as to why, when you have a 64-bit OS installed (ex: Vista x64), IE defaults to the 32-bit version? Are there drawbacks to using the x64 version of IE (IE8, specifically)?

"I guess it's becoming less of an issue these days, but initially there were no plugins that supported native 64-bit browsers (so you couldn't see Flash animations in 64-bit IE, for example.) So that's most likely why 32-bit is default.

Edit: I haven't actually tested a native 64-bit browser for a while, but since Adobe has said they're working on a native 64-bit player for a year now I assumed it must be out, but that might not be the case. Does anyone know?"
