Well, there's good news: new iPad buyers will find a small but interesting assortment of Retina-ready iPad apps in Apple's iTunes Store, which already lists nearly two dozen apps that have been optimized for the tablet's high-res display. Here are some noteworthy selections:

SketchBook Pro for iPad

Version 2.3 of Autodesk's professional-caliber drawing and painting app supports the Retina display, and features a canvas size of 2048 by 1536 pixels with 6 layers. Other enhancements include improved pan/zoom performance and 30 levels of undo/redo.

Star Walk for iPad

This uber-cool astronomy app is ideal for Apple's "resolutionary" display, and developer Vito Technology has wasted little time in releasing an optimized version. Featuring new, high-res textures for constellations, planets, and satellites, Star Walk can display up to 200,000 objects on the 3rd-generation iPad's screen, compared to a mere 10,000 on the iPad and iPad 2.
