Good news for a change!
Previously SecondLife refused to run on the Vaio because of video driver issues. Steve Clayton had kindly offered to help out at MIX07 but that won’t be necessary now because the new driver which Miel emailed me about, fixed the problem (after I uninstalled and reinstalled SecondLife and restarted the Vaio!).
I have already wasted the morning grappling with Windows Live OneCare, I might as well blow the rest of the day now trying out SecondLife on Vista!
