There is nothing wrong about copying features at all
. Not even a little bit. It is no more wrong than making a chair with four legs and cushion, or a car that has cup holders. For decades the idea of touch screens was just common and ambiguous and obvious as flying cars or controlling your TV with your mind. So Apple did it first. Who cares. Who did it first doesn't matter even a tiny bit. Who did it better doesn't matter even a tiny bit.
To pretend there is some right to vague ideas about technology is ridiculous even if it is currently upheld by equally ridiculous courts and outdated patent laws.
Also your argument that Microsoft (or any company really) is trying to somehow fool you into thinking this is new and revolutionary is so stupid it makes me think you might actually fall for it. It's called Marketing. Watch any car commercial, they all act like it is the most advanced, super awesome piece of technology to ever exist. Why would tablets or PCs, or sports drinks or tennis shoes be any different?
Also every brand (even MS) has fans. The reason you haven't met any is the same reason I don't know any Justin Beiber fans, you don't associate with them. That doesn't mean they don't exist. When it comes to fans of a brand the difference lies in how much their own identity is tied into the products they buy.
And that's really what my overall point was. Anyone who spends so much time arguing over things like who did what first in an attempt to rationalize and justify their own purchase, or worse yet justify their devotion to a company in which they have no actual vested interest, is doing so to convince themselves.*
They are also the only ones who actually care. But like you so perfectly said you've never seen a devoted Microsoft fan.
* They could also be doing it as a cheap way to get lots of comments and +1's on Google+
