The point is that i need a big screen for browsing coding etc. - in my pocket - Jtablet is too big for that, plus it doesn't have 3g.
There was something called UMPC in the past, I want something similar to those that fits in my pocket that's all.
Look at Note 4, Nexus 6, Iphone 6 plus etc. - almost every manufacturer has one these days, except the lack of HW keyboard + Sailfish on it (maybe Sailfish launcher?),
and those devices are the big hit ...
