re: Should Samsung Ditch Android?
IMHO, Craig's line about fixing it before it's broken actually stops a bit short of today's reality. The slogan is "break it, then fix it." That said, I don't think Samsung would be dumb enough to shift to Tizen unless it has to, and I don't think Google is dumb enough to force the move. Afterall, Google built Droid as much as a hedge against Microsoft's foray into hardware and a threat to Apple more than as a means of generating cash for itself -- and that strategy has worked briliantly on both fronts.
Yes, Google bought Motorola, perhaps as a fallback plan as Microsoft grows cozier with Nokia or to build customized Droid phones for the police/military market. But it's hard to imagine Google betting its entire Droid franchise on launching a new consumer phone into an already jam-packed marketplace where margins are shrinking and the future is, at best, even more competitive. Instead, it should be delighted that so many manufacturers are tripping over each other to take on that risk, propelling Droid to its industry-leading position.
I can't think of anything that Samsung could do to shoot itself in the foot than to abandon the 650,000 Droid apps out there and try to convince consumers that they should take a chance on an OS with almost no apps. (That doesn't seem to be going well for Microsoft so far.) When consumers show up in retail stores, the first question is: "Droid, iOS, or, perhaps, Windows?" Not "Samsung, Apple, or Nokia."
Would Samsung want to risk its current success on adding Tizen as a distant fourth horse in the OS race when it's already running out front in hardware?
