One of the things that bothers me about working on my laptop is that I’m confined to only a single screen. Yes, most people do work off of a single monitor, but when you’re used to using two (or even three) screens, everything starts to feel cramped on just one. Well if you have a fancy tablet running either iOS or Android, you can use it to extend your desktop.

Thanks to a $5 app called iDisplay you’ll be able to use your existing WiFi connection to sync your tablet to a desktop or laptop computer. You can then use either your mouse or the touchscreen to move the pointer on the tablet. Best of all, it works with both Mac and PC platforms. Definitely a must-have app for any tablet owner.
