Yes, there are browsers that use the IE rendering engine rather than roll their own. Firefox actually has a plugin you can to allow this as well (though I don't really know why you would.) Other browsers, like Opera and Firefox are completely separate programs that do not use the IE engine at all by default.
Personally, I think we'd all be better off if everyone just completely abandoned all microsoft products entirely, but what you said is untrue. Yes, it's difficult, if not impossible to actually remove IE from a windows system. That is by design, as microsoft makes extensive use of proprietary crap to destroy its competition by leveraging vendor lock-in as much as they can get away with. However, what you stated is simply not true.
Hmm, I didn’t know that.
IMHO, sw today is junky by design; too complex, too wide open in terms of security. Insecure by design. Even networking - what a bad joke of security.
The 400 showed that things can be secure and solid.
But now we see that security seems to be the last thing those “in charge” want.
When they started putting web stuff in the newly renamed “iSeries”, oh boy, what a joke.
Like building a model t on top of a maybach.
