Microsoft will be here for years...and years...and years to come. I'll be shocked if I live to see the fall of the empire.
And macintosh doesn't offer Microsoft any competition. MS owns like what now? 35% of Mac? something like that. Only reason that Macs have boosted back into popular eye is cause MS has poured money into them.
Though I wouldn't mind if the rebellion (google) would over throw them....
Bad star wars reference I know. lol.
