I agree that the problems were and are tractable and a company like MS *should* have been able to solve them, they have *chosen* not to because that's what makes sense to them as a business. I wasn't in the meeting so can't say why but if they had asked I would have said stick with it for all the positive points made in this thread and because they have a small but loyal following which may have swung the market at some point. However it's not my money I would be burning so I have to respect their decision.
I agree it's possible they may change their minds but that would be very different from the Lumia/W10M we talk about in this interminable thread and I'm not stretching any illusion to point out that they have a) said they don't want to maintain mobile b) stopped Lumia production c) canned (at least for now) the 'surface phone' project. Its also not stretching anything to say that for all I admire about them they have been spectacularly poor at managing mass market perceptions since the anti-trust discussions, they managed to lose a hugely dominant position on xbox and become steadily less relevant on the desktop/laptop in the face of a fast moving market they keep alienating.
I would be very pleased if they turned this around, I've been a supporter of them for many years and don't want that investment wasted, but they show no appetite for change and have become exactly what Bill Gates hated about IBM; stodgy, over regulated and short on innovative ideas. That doesn't mean they will fail, just that they won't find it easy to change as rapidly as the mobile mass market requires so perhaps the decision to move away from that market is the correct one.
