I have had the product installed for over a month now, and I have no complaints about the OS. The only issue that I have encountered is that not all of my old software plays nice with my new 64 bit OS as a result I wasn't able to reinstall all of my old apps. No problem I have since found alternatives for most, but still miss some. Fortunately I still have an XP machine in the house and can load the apps on that machine.
