Shrug, not my experience.
> Secondly, I found the touch screen very gimmicky. I tried using it for a week and found that my hand just hurt lifting it up repeatedly and also hated switching context from the keyboard to the screen.
Don't force the touchscreen. Just use it when it makes sense. I've found it's a very natural way to press buttons (because you can just... press the button), particularly when I'm using the keyboard (e.g. filling in a multi-page form, or writing generally) - must nicer than pushing a pointer around to the right place. And it's nice when dragging and dropping, and there are a few games that play nicely that way. And being able to draw/write on it is very nice occasionally. But sure, most of the time I don't use the touchscreen. But even if you ignore the touch aspect, it's a beautiful screen. I've also fallen in love with 3:2 - it seems to strike the right balance between vertical space for development and rectangular enough for watching movies on. At least for me.

That seems like something that shouldn't be happening, assuming your hands were clean? It doesn't happen on mine.
