Anyone have any in-sight to this that have played around with this?
I'm going to present a rather different point of view of this whole situation...
I would argue that - despite the fact that sellers of such devices frequently show them off by running a GUI desktop - if you're actually running X Windows and a browser on a PiTFT-style small LCD screen, you're not really using it appropriately or effectively. It is possible
to run a general purpose GUI desktop on such a screen, just as it is possible
to ride a unicycle to work, but neither is a good use of the strengths of the devices and in both cases there are widely available solutions that are better for the general case (larger monitors, and cars or public transportation).
The place where the smaller direct attach (GPIO/SPI interfaced) screens really shine is with custom task-specifc GUIs constructed out of something like Pygame or Kivy or Tk or Qt. You can make a device that handles a specific task or handful of tasks better than any off-the-shelf solution could, while exercising absolute control over every pixel on the screen.
A particular weakness of the PiTFT displays (and similar ones from other manufacturers), inherent in their design, is poor frame rate for complicated graphics; they're pushing a lot of graphics data through an interface (SPI) not designed for such a use, and it's necessarily coming from the CPU, not the Pi's dedicated graphics hardware. I'm not at all surprised that youtube videos look bad.
Using them as custom information displays and control panels works fantastically well as it plays to their strengths (I have several in my house being precision clocks, weather displays, and lighting control panels); using them as general purpose desktop interfaces will likely lead to frustration and disappointment, once the brief initial "gee whiz it works" period fades.
