I get a lot of question as to when Vista Service Pack 1 will be out. Here is the answer I received today:
March 18, 2008
SP1 available on Windows Update, Download Center, MSDN & TechNet
April 18, 2008
SP1 pushed via automatic download
Also, many of you know I am a no bullshit kinda guy so I believe there are things that need to be fixed with Vista and, thankfully, SP1 seems to address most of these issues. That notwithstanding I KNOW that Vista is certainly the most secure OS I have ever used and hella lot easier to use than older versions of Windows. Just my .02.
