I’ve had the beta of Vista Service Pack 1 running on two different Table PCs (2710p and X61) for three or four days. All in all, my experience with the beta has been pretty smooth. I experienced one bluescreen early on, but I honestly expected some rough stuff since it is a beta service pack. Any beta service packs I’ve ever installed have been pretty rough – it comes with the territory, especially this early in the process. Except for that one bluescreen, my experience has been pretty smooth.
A couple of readers have asked me about battery life – I have not seen any degradation or improvements in regards to battery life.
I plan on continuing to test the service pack, and hopefully get that bluescreen to appear again so I can report it to Microsoft.
