Hmm, at a quick glance you seem to have gotten most or all of those corrections merged in.
The one glitch that keeps standing out at me is the rapid alterations between singular and plural -- within sentences -- in referring to companies. The first example is in the very first sentence. "Microsoft" is first singluar ("Microsoft is") and then plural ("they"). The reader tends to suffer whiplash, after a while.
Excellent job, by the way.
