They still have a commanding market share in many areas...
And that's the exact reason you're unlikely to see them reinvent themselves the way Apple did. Apple did it because they had no choice - they were getting their asses handed to them in every sector they were in, they were haemorrhaging money and were on the verge of bankruptcy. It was a do-or-die move.
Microsoft have no need to copy them. They may not be raising the roof on the stock indexes, but they're still making money and because of that, inertia will mean that they'll never look at the kind of radical solutions that Apple did; it's easier to play the safe game and make smaller profits for less risk.
Why? It's a country looking to lead the world in censorship, to protect protect politicians and religious sensibilities.
Hang on, we're still talking about India here, right?
Fully rectified 240V AC RMS is already very close to 380V DC
Uh, no. No it isn't. Not even vaguely, in fact. 240V effectively *is* the DC equivalent (ignoring rectification losses), the PMPO (ie. peak voltages your 50 or 60hz sine wave actually hits) will probably be around 380v though. If you want 380VDC, then you need the same or more AC.
Love makes the world go 'round, with a little help from intrinsic angular momentum.
