For anyone interested:

Microsoft as now relased the latest and greatest version of Expression for Windows - and it's FREE!

It's says BETA and Preview Version - but it's an offical build - and it doesn't seem to have any limitations on how long it will run.

For those of you who don't know - Expression is a bit of a different vector application, in that it enables you to mimick natural media, and still keeping it vector. Check out the adjustable stroke types - cool!
