When Samsung first launched the Note 10.1, it had some really solid ideas, but didn't do so well with the implementation. Soon after, the company released the the Note II, which improved on how it handled a lot of things that seemed to miss the mark on the Note 10.1 - namely multi-window, which allows more than one application to be run side-by-side.
Good news, though - Sammy just released a video that highlights the upcoming Premium Suite features that will be part of the Jelly Bean update, and it looks like they made a pretty major overhaul to multi-window.

Yeah, we know, Google goofed the Nexus 4 launch. It's a bummer. But if you didn't manage to get your order in, you can now obsessively check availability in your respective country using the Play Store Availability Checker. The site offers two view options: the whole Nexus device list for your respective country (link), or a list for a single device in all Play Store countries (link).
