The Maxim HD App for iPad is free at the moment, and comes with the October issue of the magazine.
Note the old iPhone App "Maxim" was always free and you could purchase issues for $3.99 each, however starting October, the iPad version is meant to replace that system for the iPad.
The Maxim HD app was previously about $5.99, but is now free with the October issue (newer issues will no doubt have a cost).

I've installed the App, and it looks like it's using exactly the same technology was the Wired app for iPad, no pinch to zoom, but otherwise nicely presented.
Nice one
