While doing some research for my previous article on using apple-touch-icon in Firefox, I came across a very odd deviation from the specification on Apple's own site. The spec for the apple-touch-icon and apple-touch-icon-precomposed states that the PNG images should be exactly 57 pixels square - approximately the size of the iPod and iPhone springboard icons. When I took a look at the HTML source of Apple's home page, there was no apple-touch-icon meta tag. Instead they used the simple method whereby you place a PNG image in your site's web root. I opened www.apple.com/apple-touch-icon.png, and to my surprise, the file was not 57 pixels square - it was 129.
I don't know what to assume from this, but I can only predict what I think the reason for this difference may be: the rumored Apple Tablet! 129 pixels would be a great size for tablet icons, because the current standard icon size for web apps is 128 pixels.
Personally, I would love to see what Apple is cooking up with this whole thing. They wrote the specification for the touch icons, so there is no good reason to deviate from it - unless they are planning for another specification that would be backward compatible with the iPhone one.
What do you think? Is this solid proof that we're going to see an Apple tablet soon?
