While he is indeed trolling, or just getting angry and speaking irrationally. But, does MS SQL Server 2012 works on XP? I think so. Does IE8 and IE9 Tech Preview runs side-by-side? I think so. Does competitor able to support popular XP and latest OS? I think so.
Should he switch to Chrome and never use IE again? Maybe.... because MS doesn't care about him. And why would he want to tell Chrome users to move to IE when IE doesn't work on so many Microsoft OS? The most logical answer is, use FF/Chrome all the way. The fact that he desire this is because he still cares about IE, but, that's an irrational reaction.
