I've used everything from iPhones to the Note and I personally like the OG DInc (3.8) and DInc 2 screen sizes. Larger than 4" and I can't get to the top right corner of the screen one handed with out juggling the phone a bit. (I'm left handed) And since the top left hand corner is where all the menu options went, I use it a lot.
I wish it was more like the One X in specs with a 4"screen, but the One S is good too. If it has the One series camera, like they speculated it might in the log post, that will be a big plus.
EDIT: It would be nice too if they started putting decent batteries in these things too. 1700 is not going to be big enough for heavy usage. At least it has a removable battery and Sideo will have a 3800 for it soon.
