It’s kind of cool, but it’s not there yet. I tried it for a couple of hours before giving up. It’s great for casual web browsing, but it doesn’t handle a lot of Web 2.0 technologies very well. Pages with embedded video, whether running or not, load and respond very slowly. It doesn’t like interactive PHP applications, such as WordPress and phpBB, at all. Maybe I’ll try it again in a couple of months.
Update 1/23/08: Installing Chrome (or maybe uninstalling?) also broke hyperlinks in Outlook. Clicking on a hyperlink produced the error, “This operation has been canceled due to restrictions in effect on this computer,” as if a new security policy had been applied. In order to fix it, you have to reset the program associations in IE and make it the default browser. See this KB article at Microsoft.
