The only thing MS has a monopoly in is the desktop / laptop market and that is a shrinking share of the overall pie.
Every IOS device runs Apple software so perhaps MS is still bigger software wise but the gap is shrinking quickly
Do they even have a monopoly there? Macs and Chromebooks (+whatever linux stuff) is quite popular.
Speaking of monopolies I am seriously considering purchase of a certain Chromebook because it packs in a 1080P IPS display for ~$300. At the time I wanted firefox so I wondered if Chromebook can run that...answer is no, Chrome OS can run Chrome and no other browser at all (the excuse is Chrome IS basically the OS, I guess)!
Thought that was funny given all the crap MS has got in for even bundling it's browser, let alone making it the only one possible to use.
