Your PlayBook apps will now continue to run even after you've navigated away from them.

The current version of RIM's BlackBerry PlayBook tablet is Wi-Fi-only, though , and others are expected this summer. As such, you'll want to familiarize yourself with the various PlayBook Wi-Fi settings, since you'll presumably be using Wi-Fi often.

When, or if, you connect a BlackBerry smartphone to your PlayBook using BlackBerry Bridge, the tablet automatically imports your Wi-Fi profiles, so you don't have to re-enter all of your network information.

But sometimes you're in areas with more than one available Wi-Fi network. Thankfully, the PlayBook lets you prioritize your networks, so you connect to the network of choice first.
