While on both my PCs we see the VeriSign seal:
They both have the Norton-branded verification page:
I'm not sure exactly how long it takes the seal to propogate. I cleared my browser cache and still got the VeriSign version, but that may have to do with caching further upstream. Or maybe Symantec is sniffing browser versions and has rolled it out the Mac first. Kind of a phased approach.
Anyway, it's just a matter of time before the more than 100,000 web sites displaying the seal are sporting the second, yellow version in place of the original red one. I'll let you know when I can get a Norton seal on my PC.
