The most recent update for Android's Jelly Bean has some pretty cool new features, like better panoramic photos, gesture typing, and wireless sharing. From a security standpoint, though, the best new feature is the ability to add multiple users to one device. You can create up to 8 different accounts on Android tablets like the Nexus 7 or Nexus 10, so besides saving time hiding or protecting sensitive data, it could also save you some money. You can share a device with your family, kids, or significant other and just buy one (which may be something to think about for Black Friday this year). If you have family members who frequently ask to borrow your tablet, this feature could save you a lot of trouble. Each user gets a profile with their own background, apps, and widgets, and you don't have to log in and out to switch back and forth. Right now, it only works for tablets, but people are much more likely to share tablets than smartphones anyway. Here's how to use it. How to Set Up Multiple Users First, open Settings. Under Device, select Users. In the upper right corner, tap Add User. From here, the process is pretty much the same as setting up the tablet. It'll ask for basic info like name and email address, then have you set up a password and security questions. Once the account is set up, each user will have an icon that you can use to switch back and forth when logged in. To switch, all you have to do is pull down the settings shade and tap the user icon, which will put you back on the lockscreen. From there, just choose which account you want to switch to and enter the password. So, what do you think? Will this convince you to share your tablet, or do you still prefer to have your own?

Thousands of Android users have been disappointed to learn that getting the latest firmware update isn't as easy as it sounds. Some really popular phones like the Samsung Galaxy S III just started getting the Jelly Bean upgrade, with the update continuing to roll out over the next couple of weeks overseas. All of the stateside S3 users will have to wait even longer for Android 4.1.

If you're one of the unlucky ones who has a recently-bought Android phone that doesn't have or won't be getting the Jelly Bean upgrade right away, Motorola's got you covered—at least, when it comes to Motorola devices.

On Friday, they launched a buyback program that lets you trade in your Motorola smartphone for a $100 credit towards a new Jelly Bean equipped model (from a pre-specified list) via Verizon Wireless gift card, Motorola Visa prepaid card, or carrier credit.

Here's the list of devices that qualify for the buyback program:

• Droid 3
• Droid X2
• Atrix 4G
• Atrix 2
• Admiral
• Cliq 2
• Milestone 3
• Milestone X2
• Electrify
• Photon 4G
• XPRT
• Titanium
• Triumph

And here's the new Jelly Bean equipped phones that you can trade them in for:

• Atrix HD
• Droid RAZR M
• Droid RAZR HD
• Droid RAZR MAXX HD
• Electrify 2
• Photon Q

If you have one of the devices on the list and want to upgrade, head over to the Trade Up page to get started. You can find a full list of the Motorola devices that are or will be supported by the update here. If yours is on the list, but you haven't gotten the upgrade and don't feel like waiting, you can always try flashing it meanwhile.
