Our friends at Joy of Tech are on a roll, with this comic suggesting a variety of devices that Facebook is working on. Our favorites: The Wi-Fi-enabled Facebook garbage can that uploads pictures of things you throw out to your profile, and the Facebook showerhead whose default privacy settings "stream the stream" straight to the entire Facebook community.

Though it's disappointingly out of stock until late November, the ThinkGeek TK-421 iPhone Case with Flip-Out Keyboard certainly looks interesting. While its aesthetics and added thickness aren't impressive, the flip-out keyboard works via Bluetooth with your iPhone 3GS or iPhone 4 to provide the tactile typing sensation that some recovering BlackBerry addicts crave. The $49.99 case is an original ThinkGeek creation and uses its own built-in, rechargeable battery.

Google makes Android out to be an open platform, in contrast to Apple's closed one. But a lawsuit filed by Skyhook Wireless, a firm that turns Wi-Fi signals into geographic coordinates for mobile devices, alleges that Google pressures handset makers by threatening to withhold access to the Android app marketplace, use of the phrase "Android-compatible," and full access to Google apps on the phone. Skyhook says Google forced Motorola and another phone maker to break deals or risk those losses.

If you find yourself carrying your iPad around town a lot, there are plenty of cases that will hold it. But what if you just want to drop it in your pocket and go, as you would an iPhone?

Marketing firm Dentsu London uses stop-motion photography and custom 3D software to create a movie that features animations in light, projected using iPads (you know, that limited entertainment device that can't be used for anything creative).

Opening a PDF containing a maliciously crafted TrueType font in either Adobe Acrobat or Reader 9.3.4 could result in arbitrary code execution or a crash. Although the vulnerability affects all the platforms on which Adobe Acrobat and Reader run, the current exploits in the wild target only Windows. To be safe, rely on Apple's Preview, Smile's PDFpen, or another PDF application until Adobe closes the vulnerability with a 4 October 2010 release.

The iPod nano has finally shrunk enough to live in the most obvious spot on your body - your wrist. iLoveHandles is selling the $19.95 Rock Band, a leather strap to which the new iPod nano clips such that it looks just like a wristwatch. Now we're wondering if there will ever be an iPhone nano that could be attached in a similar fashion.
