Why I'm here?
I had the perfect combo with SP1&2, W8.1, and L925/930.
I had office on my phones, OneNote and everything was in sync via Skydrive/OneDrive.
The touch/pen experience on the SP was perfect w fullscreen metro IE etc.
The package was unique for Microsoft. It was not possible to get this on any other ecosystem. Any invested money (as a customer) was well spent money.
Now, W10 has ruined the touch experience of the SP, OneDrive is just a shadow of what it was, W10M will make the phones bleach Android copies and the Office package is better on ios and Android. I.e, I feel I did chose the wrong system. MS seems to give up what they accomplished with W8.1, SP and WP.
The best product mix today seems to be a boring iPhone (fastest, most polished, the best office and less "will come in the future" BS) a SP with the mediocre W10 or "old W8.1" OR if you can live with it, iPad pro and an iPhone.
Add to that that WP/W10M is so extremely slow adding features and that the new stuff (Cortana etc) is not even available but Siri is (Sweden). And no new interesting hardware has been released for ages.
I feel betrayed by Microsoft/Nadella.
