Todd - our silver tongued product planner and author of many of the posts below - recently did a recorded interview with Ian Dixon for The Media Center Show on TheDigitalLifeStyle.com. Take a listen for some great insights about the product philosophy, as well as details about specific features. The interview starts at about the 12 minute mark.
Also...today Computerworld's Scott Koegler posted a very comprehensive (and very positive) evaluation of Home Server. His bottom line: "Its simplicity and automation will make it a winner with many home users....For my part, now that Home Server is installed on my network, it's not going to be unplugged."
Simply put - Windows Home Server is just AMAZING! I love the Beta :)
