Re: It would actually be a smart business move for Ms
For home users perhaps, Firefix and Chrome are tinned worms for the enterprise due to the number of weird and wonderful business critical web apps* we have to support and often bork at every increase in version.
I'd be happier if they bundled some sort of browser for reading local html files(read me's/help files) - but accessing something outside of localhost would prompt to choose an internet browser. Something like you can open docs in wordpad, but it's likely you're going to use open office/MS office/libre office/a.n.other to do any writing in real anger.
*Not our choice to run them - and the dev team probably no longer exist!
