As you might have heard Apple’s new iPad landed last week, complete with its high resolution Retina display. Four times the pixels as the previous iPad means that there is much to be gained from apps moving to high resolution art and doing what they can to take advantage of the upgraded display.For its part, Apple is using the App Store’s front page to highlight apps that have been updated to take advantage of the new iPad’s 2048×1535 resolution. These are mostly popular apps from big names that had the resources, information, and access to turn around their app updates in record time. For doing so they got to have their apps highlighted, Apple landed some selling points for their new devices, and early adopters received some shiny new apps to play with this weekend.Some of the highlighted apps include:KindleNY TimesFlipboardReederTwitterVimeoReal Racing 2 HDEvernoteInfinity Blade 2It’s a pretty solid list overall. The selection is just 42 apps right now, which includes some games, productivity/learning software, and then a fair few content consumption apps for both watching video and reading. The prices are on the high side (for the App Store that is) on average, but that’s a combination of these being premium apps and being the iPad version, which typically sell for a higher price.Some of the apps that were updated but aren’t being highlighted in the section are Apple’s own software, like GarageBand and iPhoto. These look superb on the new iPad, but they get enough promotion already, so Apple is sharing the limelight a bit.My favorite update to an app was the one received by Instapaper (my favorite app). The version 4.1 update brought along a number of high-end new fonts, a full-screen reading mode, and a responsive background color (twilight sepia). The big change was really compatibility with the high resolution display, making for crisper text and better reading conditions than before. The iPad 2 was no slouch when it came to text, but the new iPad takes things a whole new level.Of course for all the iPad apps that were updated, thousands of them weren’t. Some of the ones on my Retina display-compatibility wishlist include Sword and Sworcery EP, Food52, Kingdom Rush HD, and — most of all — Google Earth. I’m sure it’s just a matter of time until all these have updated (though older games are questionable). While non-Retina display apps look more then adequate when on the new iPad, this is an arms race and developers have to keep up with the hardware if they want to succeed.
