Now have Windows 7 RC on my laptop – and Windows Server 2008 R2 RC on my main desk workstation.  I use the laptop quite a bit as I spend a fair bit of time not in my cube in Sammamish but on campus or sometimes telecommuting from home.  I am fortunate that my R2 server has a couple of video cards and supports up to 4 monitors – although for now I just have 3.  Now when I am at my desk I can remote desktop to my laptop – and use all three monitors.  Very cool!  Or if I am in someone else’s office and can borrow an external monitor I can bring two screens from my desk machines – complete with excellent graphics and sound!
