Unfortunately, it won't look great on a lot of displays since it's using subpixel anti-aliasing for fonts. Examples being retina displays doubling the size of the pixels or a tablet turned on the side.
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.
