Internet explorer testing for mac and linux

Okey, so the question has probably been asked before, but I haven't found an answer. If I don't want to use a virtual-machine or crappy screenshot-webpages how could I test web-development for IE? Shouldn't Microsoft supply a tool for web developers to test their products? Because more and more people are developing on mac and li开发者_如何学运维nux and don't care about testing on IE until the end, and therefore misses a lot of bugs.

You could use IEs4Linux: http://www.tatanka.com.br/ies4linux/page/Main_Page (wine)

But this is really crap.

The best option will be to setup a virtual machine. ;)

We have in our company, one virtual machine for every IE version.

In that case, Wine is pretty much the only way to go.
WineBottler has nice predefined prefixes to run Internet Explorer on OSX using Wine.
It's extremely easy to install.

[October 2012]: A friend told me about browserling.com today which seems like a perfect solution (free + subscription). I wrote about it more in this thread: Best way to test a webdesign for IE on a Mac?
