So I let the little Apple software update install the latest Safari v3.x on Vista on my MBP this weekend. In a client gig today someone was looking at this blog on ZDNet which prompted us to gather around and check out Safari on my machine. HOLY CRAP, I'm WAY impressed. Check out the perf. numbers on Safari over the others!
The coolest part has to be the developer Web inspector. Turned it on for my blog... check out these screenshots (kinda Firebug-esque)... very slick, think I'll give it a shot for a few weeks.
