Opera is good, I use it as my primary browser but have to keep IE on hand for some things. Opera doesn't work well with some pages that have ActiveX controls. For example if you are putting something on Ebay to sell and want to include a picture of it, the ActiveX control for uploading a picture to Ebay does not work with Opera. I have also had some trouble with certain flash pages. My other gripe with Opera is that it doesn't have an option to save a web page as a single file like IE does with it's .mht format. You have to save the entire web page then zip the html and pictures together if you want it in a single file. I still use it for most of my surfing though, and just switch to IE for those few problems pages. Overall I like Opera better, it seems to have a lot more useful innovations where IE seems to have won the browser race and quit.
