If you interested in a test drive of the technologies around the Wave 14 launch, take look at the VM made available from Microsoft.

2010 Information Worker Demonstration and Evaluation Virtual Machine

Note:  It is important to understand you will need a system with Hyper-V to import this VM and get it off and working.  Also, make sure you keep a copy of the original unpacked VM as this is based on a trial version of the OS (time bombed) and there is a chance to rearm the VM, but you are better off either keeping the original files or taking a snapshot as soon as the VM is living in your Hyper-V environment.
