There are lots of post flying around the tech bogs about the Windows 7 Beta that's out. From what I read, the reaction is quite positive, not that I've given it a spin myself, but by the sounds of it, it's much improved over Vista; mind you that's not hard as Vista is pants.

To be honest, after sacking my 5 month old Vista desktop and employing a nice new MacBook Pro to replace it. I got fed up with sluggish performance and this constant battle of trying to get Vista to let me do what I needed so I'm not sure I'm in a big hurry to try another new Windows out at the moment and the other PC's seem quite happy running Windows XP still.
