How to Optimize Your iPad Use - The iPad is loaded with all kinds of features you’ve probably heard about, but look a little deeper, and its extra abilities might surprise you. Some of these secrets are enabled through apps, while some are built into the device already.

Turn Your iPad into a Secondary Desktop Display - With its big, high-resolution display, it’s a shame to just park an iPad when switching to a computer. Instead, Air Display ($10) makes your iPad a second screen for your Mac, extending the desktop. The tool has just been submitted to the App Store and should be released soon; I checked out a beta.

Stream Movies From Your PC - Even if you bought the largest-capacity iPad, if it can’t fit all of your videos, it’s too small. Instead of trying to cram everything into the device, you can stream videos from a local or online PC. The process has one main caveat; if you bought movies or TV shows from the iTunes store, DRM restrictions block those files. (Podcasts and music videos should work.). But you can watch your own videos or DRM-free downloads without taking up iPad storage.

Connect More Than a Camera - Apple’s iPad Camera Connection Kit ($29) does so much more than its stated purpose. Instead of just transferring photos and videos from your camera or SD card, the adapter’s USB port attaches a range of devices.

Supercharge the Browser - Safari set a great standard for mobile browsing, but many alternatives reveal its missing features.

Atomic Web Browser - Safari will unfortunately remain as the iPad’s default. However, you can create a bookmark that reloads a Safari page within Atomic Web Browser. In the Atomic Web Browser Settings menu, tap Install Bookmarklet. That’ll open Safari and explain the process.

Apple’s eBook reader "iBooks" - keeps all of your Apple purchased books together, includes an iPad-specific interface, and interfaces with iTunes. iBooks uses the ePub file format, so while the iPad can read PDFs, you can’t store those files here with the rest of your books. You can, however, convert them to ePub first, and keep everything in one place.

Print from an iPad - PrintCentral - iPad printing might arrive in the future, but you can still print hard copies today. Several apps download network or online files to the iPad and can send them to a printer. Some apps even edit documents first, but many are difficult to use.

Instapaper Pro - Whether you have a 3G version or not, your iPad faces certain situations where it can’t be online: planes, train tunnels, and other network-not-found destinations. You can still keep up on all of your favorite Websites with Instapaper Pro ($5). This tool manages content you want to read later and caches articles for times that you’re offline.

ProRemote - A keyboard and mouse combination remains the best way to control a PC, but those days might be numbered. What if you could use the iPad as an interface, changing PowerPoint slides while reading your notes, or even touching faders and dials to interface with pro audio production tools?
