Good thing I stopped by my Vaio's Support Page today since otherwise I would not have noticed that main software updates I've been waiting for have been posted.
The only thing left now is to wait for that Vista Update DVD to come in the mail (for God knows what purpose), since I already have Full Vista Ultimate installed already.
So, all of you who are waiting for your computer manufacturer to issue some updates - it's about the time to check those support sites.
If you got Sony VAIO SZ-370 like I do, you can go to http://esupport.sony.com/US/perl/model-swu.pl?mdl=VGNSZ370PC, and for all other Sony's just go to http://esupport.sony.com/
