Lots of people have now blogged about the availability of Vista SP1 on MSDN Subscription, but what is new and when will it be available for the public? I Googled around a bit...
Mike Nash on the Windows Product Management group blogs on the Windows Vista Blog:
With Service Pack 1, we have made great progress in performance, reliability and compatibility.
...
...with SP1, copying or moving files around your PC, your home network or your corporate network should now be much faster.
...
In addition, on many kinds of hardware, resuming a Windows Vista-based PC from sleep is faster on Service Pack 1.
...
we will begin making SP1 available through Windows Update in mid-March
Mike also writes about better support for hardware, which is about time ;) There's a pretty good page on Technet which describes the Notable Changes in Windows Vista Service Pack 1.
