For me there is such a thing as a screen that is too big. I would hate sitting up close to that thing all the time. The S1 example with everything on the one screen but just way bigger just looks like a big cluttered mess to me (admittedly not helped by the fact that IMO S1 is so fugly to start with). I can see how hi-res stuff is maybe good for tv or games, but I still wouldn't want to be sitting that close to it and if a regular sized screen on the desk right in front of you is too blurry for you, then the bad news is that's probably more to do with your eyes than the screen.?
If it works for you then great, but it does absolutely nothing for me.
