I use windows phones (because no one else will)
I still have a windows phone (my 6th, currently on a lumia 640 after an 820, an HTC mozart7 and a bunch of Orange SPVs. I even tried a samsung ativ S but the RAM...) and I'm genuinely concerned about only having two choices of phone (iOS and Android), and the massive cost of ownership, in the near future.
My plan is to buy up a bunch of 640XLs (or 950 XLs) cheap and then run them into the ground, and yes, the price of the Elite X3 put me right off.
