MS Vail, or WHS2011 as it's known, gimped in my opinion because it LACKS Drive Extender, now potentially getting it via a 3rd party add-in? How can Microsoft NOT get it working, but someone else can? http://www.mswhs.com/2011/02/drive-extender-functionality-coming-to-whs2011/?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+MSWHS+%28MS+Windows+Home+Server%29

My biggest concern is how would I even install Vail on my current WHS, there is no way I can back up damn near 8 Terabytes of data BEFORE installing it, it's all on DE at the moment. :(
