Very sorry to double post but no EDIT button and I missed something.
Someone mentioned about the easier way to get updates for IE. I don't really how large an update could be but frankly I think it could sum up to be as much as an Opera version. You click update and download. OK, i go to Opera's website, download the newer version and install it NORMALLY. Acts as an update. it ain't that much harder. Besides, what happens for some reason Windows need reinstall due to a MAJOR crash or whatever? After reinstall you'd have to click UPDATE again and wait again whereas I can simply install the newest version and forget about it. In this situation time lost to updates is kinda equal. Besides, IE update would most likely want a reboot. The other choice is downloading the updates manually and installing them manually. That way you eliminate the part of having to download the same update over and over. But installing them one by one would take more time than downloading a newer version of Opera or FF. Of course you could save time and not update but you don't want to be like swiss cheese - full of holes, do you?
So don't involve this IE 'advantage'. It's actually worse than FF and Opera. IE is, THE LEAST, as good as the other browsers, NOT BETTER concerning updates.
