While iPhone users have been benefiting from some of the new iOS features such as multitasking for a few months now, iPad owners have been patiently waiting for today’s launch since iOS 4.2 was announced back in September.

In case you’ve forgotten in the intervening months, here’s what’s in store for you if you connect your iPad to iTunes later today (after 10 AM PST):

• Multitasking: double-tap the home button and a scrolling list of all your open apps shows up at the bottom of the screen, letting you hop between apps
• Folders: sort all those apps into logical groups by dragging one app onto another. The new group can be renamed, added to, edited or deleted. Up to 12 apps per folder.
• Unified inbox: All of your mail accounts can show up in one combined screen, or you can see them individually
• Game Centre: Apple’s answer to Xbox Live and Sony’s PlayStation network
• AirPlay: If you have an Apple TV, you can stream any video playing on your iPhone or iPad (or iPod Touch) to your TV over WiFi
• AirPrint: wirelessly print from your device to any available network printer that supports the AirPrint feature
• Find my iPhone (or i-Device): this previously subscription-only service is now free and helps you locate a lost device and/or remotely wipe its contents to keep it from prying eyes

You can bet I’ll be getting this update ASAP and be back to tell you what I think, but in the meantime, please leave your thoughts below.
