I used to recommend Parallels to my clients but this is pathetic how buggy this software is and NO updates in over 2 months. What is going on?
go here. http://www.parallels.com/en/support/beta-testing Fill it out and wait for them to get back to you. Bear in mind, they ask for your forum login name, I assume they are looking to weed out the people who bitch about everything and are actually looking for people who post constructive information. Of course, I could be 100% off base there.
I could imagine Parallels demonstratinig both OpenGL and DirectX acceleration inside the VM with Coherence turned on at WWDC spark a whole lot of interest.
