As the title suggests I'm considering upgrading to the 950. I know the 950 is higher spec in every department but will I really notice any difference? If anyone has any experience of both handsets their input would be greatly appreciated.
the only real thing here is the camera, so if you are going to take photos and you want them to look nice on low light and all that, 950/XL would be the best choice. about the performance and all, Windows 10 runs really nice on 640, extremely well even if it doesn't have official firmware and this and that.
but I think they key factor for your decision should be the camera... Camera on 640 is not bad, but it's not great especially if your light is not natural, also front facing camera is not that great on 640 either, it does the job for videochat though.
The other stuff is better on 950, but it's just something like I don't care much about it like how the screen looks like, I usually use the phone on low brightness and put medium whenever I need to see something clear. so I never cared about screen so much.
the other factors are Windows Hello and Continuum, for some it's useful and for others it isn't. so you should really think about it.
if you are a person who doesn't take many photos, don't do videochat, don't really care about hello or continuum, what would be the point of getting 950? in some cases you might see it performing better, but it's not like it makes magic and it's a noticiable difference.
Last time I saw how 550 is slower than a 535 on Windows 10, but in the end you could notice the difference because it was side to side. but both performed well, and 640 was little faster but not too much.
so what I mean is performace should not be the key thing here, maybe on games or something 950 will do better, I really don't play games so I don't care. but on lunching apps and all, it seems it's not like you will get too much improvement.
so I would say If you have money and you care about photos and want to get really nice photos and all... just the camera is worth the price, if you don't care about photography, or hello, or continuum, then... I don't know any reason to get it.
My decision for a 950 is the camera, my personal experience, so it might be different for you. but I don't think performance would be the key reason for an upgrade, not even the screen size since it's only 0.2" but the camera and then continuum. and that's it.
