3. Dual-core 1GHz Processor & 1GB RAM
That means it’s got the horsepower to multitask, output 1080p video and run high-powered apps. The 1GB of RAM is particularly important for running applications in the background, and opening multiple tabs in the web browser, as iPad owners know from opening more than a few tabs in Safari and watching them get flushed as the iPad runs out of memory.
4. It’s got “true” Multitasking
By saying the PlayBook has “true” multitasking, RIM seems to be pointing at the fact that multitasking on the iPad is still limited in a lot of ways. Apps can’t fully run in the background on the iPad like on a full computer, they can simply perform select actions, like playback audio or finish a download in a given amount of time. The implication is that the PlayBook will let things run willy nilly in the background, more like a standard BlackBerry phone.
