Um. Any company that does that is probably going to go out of business, just like Sun. You know who's a "developer's" company? Microsoft. And if you drink their kool-aid, your Visual Studio-developed desktop apps will run smoothly across all sorts of hardware with a single compiled exe. Microsoft convincingly showed that hardware doesn't matter many years ago, in fact their focus on software over hardware is arguably why they won, and they treat their licensed software devs well regardless of what company they work for. There are many instances of "Hey Microsoft, this doesn't work" and Microsoft responding with a custom piece of software to fix the problem. Some developers are angry about Windows 8 because they perceive that Microsoft is caring about them less, and that's probably true, but Microsoft will learn again that it shouldn't upset its developers if it wants to retain its supremacy.
nope, it was their business acumen, and willingness to kill off competitors
C'mon, Microsoft just handed them an app store for the entire ecosystem. None of their technology stack was designed to do that before surely some stuff had to change.
assuming they survive, that's pretty cool.
