Hi! I'm about to buy a Surface Pro 2, but I've got a question about Microsoft's repair service. I read on a website that there is no repair service from Microsoft. They said that if you shatter your screen, they will not replace it, they will offer you a new Surface Pro for 450$. Is that true? I can accept that with a shattered screen (I’ve never broken any electronic device, not even a cell phone, so I’m not really worried about that) but what happens when the battery life is over? Will I have to pay 450$ in two or three years so that Microsoft gives me a new unit? In that case, the unit they send you is a new one or a used one? Thanks!
