MS has a problem, not a huge one, YET, but a problem..
In a way they've been lucky, desktops and laptops sales have dropped because of tablets and mobile devices, but because MS has a complete monopoly on desktops and LT's OS they still make a nice profit. But without that they would be in trouble, so far they missed the boat on mobile devices and tablets, and without that OS monopoly they would be like a Nokia, they would be a company that would be fading fast... But desktops and laptops are never going to go away completely, so as long as they're around MS has a money source. MS isn't in danger of folding, but they are in danger of becoming irrelevant in a the huge, fast growing tablet and mobile markets.. They need a winner in the tablet and/or mobile market.
MS is running a little scared.
