Tablets are undeniably great for entertainment, but if you’re using a laptop or desktop, they’re just another screen that you can’t link up — unless you invest in a screen mirroring app. DisplayPad’s my favourite of the iPad apps, if only because of the price.
DisplayPad certainly isn’t a unique app. Probably the best known of which is AirDisplay, but that’s a $10.49 app; DisplayPad undercuts it at a much more wallet-friendly $2.99. There’s also DisplayLink, which is free, but Windows only. DisplayPad has recently been updated to support Mac OS X Lion (except if you’ve got an NVIDIA GeForce 9400M card; the same bug affects AirDisplay too) and is an excellent way to shift one or two apps over to a secondary screen. My twitter feed and iTunes library now more or less permanently lives on my iPad screen this way.

Inexpensive
The Worst
Low resolution, won’t work on some Macs (yet)
