Hardware wise, I can't really find what I want with an ubuntu phone: I like the spec and the price of the Aquaris E5, but the bezel is really huge. The Meizu mx4 lack of a SD slot and the Meizu 5Pro is too costly :(

I would miss whatsapp too... Not that I like the app, but it's commonly used within my group of friends.

Fix the two points above and you've go a buyer :)
