what?!

ie = mosaic (upgraded)
moz = gecko

those are 2 completely different engine

maybe ms has gazillion of dollars and has the best browser but why can't ie manage png alpha trans and css2 then? why do i have this crapy tool to sort my bookmarks? why is it unable to REALLY delete cookies? why does ie 'themes' are fucking jokes?
btw, crazy browser is 'just' a layer over ie

main task of a brower is to render html.. ie don't follow html and xhtml specifications.. because of that a fact standard will oblige designers to code w/ mistakes..

end-user consumer don't see it, that's why ie is largely considered 'good'
