My colleague (and ridiculously knowledgeable) Harold Wong will be hosting a Windows 8 / Windows Server 2012 Installfest in Denver next week.  I highly encourage you to attend if you have an interest in getting a solid start on these platforms.  In his own words:

“With the recent RTM of Windows 8 and Windows Server 2012, I am hearing a lot of interest from people who really want to start kicking the tires of these two new flagship products from Microsoft. If you are interested in getting an evaluation version of Windows 8 or Windows Server 2012 installed onto you machine to start playing with, I can help you. I will have bootable thumb drives with Windows 8 Enterprise 90-Day Eval (RTM) and Windows Server 2012 Evaluation (RTM). In addition, I will also provide VHD files that have Windows Server 2012 Evaluation and Windows 8 Enterprise RTM 90 Day Evaluation preinstalled so that we can configure your machine with Boot to VHD (no repartitioning required and keeps your existing OS intact). I will show you how to build your own VHDs so you are armed for the future.”

This is an informal event where you can come and go at any point during the event window.
