iPad Wallpaper Web App is Near Native!
check it out on your ipad at http://ipad.imacwallpapers.com
They have a pretty good selection and the wallpapers are all really high quality. You can even download them in 1024x1024 OR 768x1024 portrait.
I was getting tired of all the ad-ridden sites for iPad wallpapers that were not optimized for the iPad and were just plain crappy.
The site itself is actually pretty fun to navigate I really like it 🙂
