M$ is not a pioneer in any field or atleast I cannot remember, they have always copied someone else's product and then marketed in such a way that entry to barrier for others was always high. Mobiles are a different game now, they are scaling the higher barrier that Nokia set by partnering with it.

PC OS : IBM first
Spreadsheet : Lotus 123 first
Networking Novell first and with Active directory was Banyan Vines (hope I spell it correct)
Mobile : Still catching up
GUI on top of Os : Apple Mac first
Mobile phones : Still no clue what to do
Internet : Unix based first
Gaming : pretty much last
anything else that need mention?
