Shouldn't tablets be avoiding subpixel anti-aliasing if they can be turned on the side? Doesn't it just _not work_?

That's a good question, and I'd be interested to know how this is generally solved (it seems the ipad just doesn't du subpixel AA). I don't see a problem with subpixel anti-aliasing if it's with rotation in mind, i.e. different rendering depending on orientation.

In context of the original post, of course, there's not much the ipad can do since the subpixel AA is already encoded in the image.

Orientation sensors allow the operating system to know how the subpixels are currently oriented and adjust the text rendering accordingly.
