I don't see Microsoft's reign on technology dimming in the future. Their business model will lead them to be successful in later years. It's still pretty awesome that Windows 7 is the fastest selling system in history, I wonder why?
It's also pretty great that 2010 is selling at a rapid rate as well considering the differences in 2010 and 2007 arn't exactly large. I personally enjoy and love using Office 2010, it's pretty, realiable, and multi-featured. I'd buy it again any day compared to Open Office, bleh!
On a side note, I FRICKIN LOVE POWERPOINT 2010!!! You can make a visual orgy with that stuff!! OMG!!
