Two points, if you are planning to get rich then buying gadgets is not the route. Even a iphone is going to be more or less worthless eventually and the worst thing anyone can do is buy the latest model every year, guaranteed maximized losses.
So the real question is, will this gadget do what I want for at least 2 years, for me I think the 950 will do just that, it has great components such as a powerful CPU, lots of ram and a world class camera that can take good quality photos in low light.
For me I'm not too bothered by apps, and what it supports now is enough so that will do.
As for the future though, I'm not optimistic, people criticize Ballmer, but he was bullish on whatever he went into and supported windows phone properly trying to tread a line between being another Apple and Microsofts traditional business model
In comparison Nadella is turning Microsoft into a "me too" company, unfortunately going for the Google option of pursuing advertising revenue rather than the Apple one of bespoke devices. I fear that for this reason we will see windows phone languish in the dolldrums at best, Microsoft's best hope now is to extend the PC down to the phone and produce phones that are powerful PC's, that takes vision (and a lot of financial risk that only Microsoft can afford), not sitting around waiting for a third party to pick it up.
