I really look forward to the day Microsoft ends up in court trying to enforce such patents. Because that is the day they'll see those blatantly BS patents ruled invalid.

...but if they're so BS why do they even get given a patent in the first place

Because in the modern age we live in, patents are never meant to be used by having a court rule that a competitor can't produce a product. They are used as devices for extorting money and threatening financial ruination from legal fees.
Whether a patent will hold up in court is almost irrelevant -- they are vehicles for revenue generation -- just get yourself a patent and then go hunting for someone you have the pretext to sue and demand some money from them to leave them alone. They will inevitably reply that your patent is silly or doesn't apply to them, at which point you simply ask "would you rather spend 5 years and a fortune in legal fees to roll the dice and try to prove that in court, or would you rather just give me a bucket load of money right now and i'll go away." Of course you don't say it like that, you have your lawyer write up some nice fancy language that everyone knows means the same thing.
