I will try the S6; it seems good but someone told me there are no really solid keyboards for it? I never checked it because I already had an iPad.

I had that issue too :) However that changed when remotemac (no affiliation) introduced me to Remotix; I live in the mountains and my internet is bad, and yet it has no latency with 4k screen transferring. Anything on Linux is just horrible compared. I develop apps on my iPad and it works really well like that.
My ‘dream’ (bit extreem but lets say preferred way of working) is to use my x220 with Linux to do that; then I can do all dev on that machine while doing iOS dev remotely. Now I still have to carry an Android tab, Windows laptop (I can do that on the x220 but I really do not like to dual boot) or iPad with me.
If your want to do portable programming I would recommend a light 2 in 1 laptop. You can dual boot Windows and Linux on it (Windows for media consumption and Linux for programming). But it is bigger then a tablet.
Of course if you use a server you can use anything you want to do programming. But personally the latency is a dealbreaker for me.
