A huge improvement on their first try at an app for tablets like the iPad. There’s significantly more content in this version than in the print, which goes a long way towards justifying price parity – $4.99 in this case. It’s not a real product yet, just a demo I hope they’ll make real. Interesting points to note: the demo device has a 16:9 screen, so this wouldn’t actually work on an iPad the way it’s currently designed. But it looks really right when used in landscape mode. Also, a lot of non-standard interaction widgets like the copy/paste selector, which might not be in compliance with Apple’s approval process.
