One big problem I had with IE was the update cycle. Whereas Chrome (and subsequently other browsers) updated every six weeks or so, non-technical Windows users just had whatever the OS installed by default, e.g. IE6, etc. So while Chrome might does have quirks and issues, the frequent update cycle compensates for it.
