I am so glad you guys kept Adam's beginning intro in. We've all been there - having to introduce ourselves before every presentation. Showing the human side makes you all easier to relate to. Great work on the show keep them coming!
My Netbook came with Vista Basic and I have been running Windows 7 Ultimate on it. Performance and battery life are noticeably better in my opinion. Not sure about Windows XP I never ran it on it. I imagine if you have an older Netbook that wasn't Win7
certified than you might see better performance on XP.
By and large though there are so many improvements in Win7 to help battery life. For instance on XP if you shut off your wireless card most of the Network services still run and take up cpu cycles (thus draining more battery). In Windows 7 there is something
new called Trigger Start services and you will find even some of the default services utilize that. For example lmhosts service will not go out and try and get an ipaddress if it sees the nic is disabled.
If I am doing any serious development though I try and plug into AC power and run on "High Performance." I need all the horsepower I can get from the little guy.
