on cue, Microsoft has made available the (long-awaited) Service Pack 1 for Windows Vista to a private group of beta testers. One lucky user actually goes on to describe the update and note a number of positive changes, some of which include a much snappier logon experience, a new option in the Disk Defragmenter "allowing you to choose which volumes you would like to defragment," improvements in responsiveness when resuming from Hibernation / Sleep modes, and interestingly enough, slightly improved battery life on a tested laptop. Furthermore, "select members of the community" are also getting to give five new "reliability packages" a whirl, which are all slated to be available to the public before SP1 is released en masse. Be sure and hit the read link for the full rundown.
