The problems IE6 had are vastly different from the problems Chrome presents. But I would argue the Chrome's are potentially worse. IE6 was a big problem mostly for developers who were perhaps better equipped to deal with them. Chrome not only has the chance to become the "singl;e browser" (if it's not already there) and direct the web wherever but it also poses problems directly to the users who are most definitely not equipped to handle them. I see this as a much bigger issue than IE ever had. It's not technical so a simple patch in your web app won't fix it.
