I bought a MS phone because my nexus 4 kept crashing with the latest upgrades. The battery would last max 6 hours, using the camera had a 50% chance of restarting the OS, the touch functionality of the screen would work 50% of the time after reboot, when the battery was under 25%, the phone would act eradically ... etc. As for iphone, too expensive. I got my lumia for 60$ on amazon without contract.
