I can't blame IE - by the numbers, its just as safe or safer than Mozilla (who released a fix for a dozen vulns a couple days ago) or Opera (who did the same last night). I use each of these from time to time. IE is a bigger target, so caveat emptor, and with any browser be careful where you go. Microsoft already released the critical update patch to address this, and I applied it, so no worries there.

For the record, I run mostly Windows Vista, and in 20+ years have only been hacked by my daughter's iTunes app (which has an attrocious security record), or my son's predeliction for dodgy Runescape installs. In general I trust Microsoft to code more securely than Apple or some of the others, and I think their recent track record backs that up - and in software, the only relevent measure is today's actual performance. ymmv of course.
