I've been running Vista SP1 builds for a while and I like them.  I don't like the process of changing builds which is "simply" a case of uninstalling the old build, letting it reboot twice, updating the registry, doing find updates in windows update, reboot, do it again, reboot, do it again, wait 15 mins, do it again, then let it install for a chunk of time, reboot twice more.  Now, you won't have this fun when the "real" update comes out, but us testers simply enjoy this process!!

Vista SP1 Confirmed for February 15 – XP SP3 Too?

Windows Vista Service Pack 1 is just around the corner. Despite the fact that Microsoft continues to point to the first quarter of 2008 as the deadline for the delivery of Vista's first service pack, it appears that the refresh will drop as early as next month.

According to the Redmond company, Vista SP1 is planned for release by the end of March 2008. Microsoft has not shifted from the official timetable and failed to update it in accordance with the development of the operating system. However, it appears now that February 15 was confirmed as the RTM date for Windows Vista SP1.
Mid February 2008 is a more realistic date for the launch of Vista SP1, and one that is at the end of the natural course of evolution of the service pack's development process. Taiwanese news outlet DigiTimes, doing a story on the DRAM industry in 2008, cited Pei-lin Pai, a spokesman for DRAM manufacturer Nanya, saying: "the PC market will rebound in the second quarter. The launch of an updated version of Microsoft Vista on February 15, if its prices do not go up too much compared to its previous version, may help boost DRAM sales," (emphasis added).

I can't comment on the date, but mid-Feb is Q1 calendar year 2007.
