I do.
as long as firefox and safari keep IE dominance in check and as a result keep the standards-based web viable, i wonder what google really stands to gain.
It's necessary for the health of the internet. A two-browser monopoly is just as bad as a one-browser monopoly.
Assuming Google implements this correctly, it will be the first damn browser to actually make syncing bookmarks user-friendly. That's a feature that should be standard by now, but it's not. The browser space is still open to innovation.
As far as what Google stands to gain: they pay millions to firefox and others for search referrals stemming from the firefox homepage and the integrated search bar. Also, Google certainly benefits from people surfing the web faster (more page views = more money for them).
That and, you know, the millions of dollars thing. That's big too.
(Does anybody else find it annoying that Google's software is always more aesthetically pleasing than their online programs?)
