Conde Nast is preparing to embrace the iPad with some of its biggest magazines. In addition to a tablet version of Wired — which we’ve covered before — the publisher is developing iPad versions of GQ, Glamour, Vanity Fair, and The New Yorker.

According to the New York Times, Conde Nast will officially announce the plans in an internal memorandum today. The publisher likely won’t be alone in dishing iPad plans over the next few weeks — Apple expects to ship the Wi-Fi-only version of the iPad in late March, and the 3G-equipped version in late April.

Conde Nast already has a presence on the iPhone via its GQ app, which according to the NYT¬† “has sold more than 15,000 copies of the January issue and almost 7,000 of the December issue.”

Because of the uncertainties still surrounding tablet magazines with consumers, the publisher will be testing different prices, advertising models, and methods of digitizing its magazines. While Wired’s tablet version was developed in conjunction with Adobe, Conde Nast will be handling digitization of its other mags internally. As expected, the tablet magazines will be sold through iTunes. Wired will also be available outside of iTunes, so it will likely be available for upcoming Android and other tablet devices.

Conde Nast appears to be approaching its digitization efforts with these magazines as a test phase. If the publisher is pleased with how these magazines perform, it will look towards digitizing other magazines in the fall.
