Another spin through the Macworld Conference and Expo on Friday revealed more software and peripherals that push the boundaries of what Apple products can do. The show, which was expected to draw 25,000 people, wraps up today at Moscone Center West.

Some highlights from the show floor:
IGrill: Among the more unusual peripherals on display is the iGrill, a Bluetooth-enabled meat thermometer that will ping your iPhone when the turkey’s done.
IDevices CEO Chris Allen is an avid griller who wanted to find the simplest way possible to know when dinner was ready; his company released the iGrill at the end of last year. The product costs $99.99; an accompanying iPhone app is free.

DJay: Algoriddim, a six-person software developer from Munich, has a hit on its hands with DJay, a music app that has a starring role in a new commercial from Apple.
Apple’s lawyers now have another fly to swat after a California man stepped up with a class action lawsuit over the iPhone 4’s glass. According to Apple, the glass found on the iPhone 4 is “20 times stiffer and 30 times harder than plastic.” Apparently none of this matters when you drop the device on the ground from three feet up.

The plaintiff claims his daughter dropped his three-week old iPhone 4 from that height and the thing busted. In the lawsuit, he claims that “months after selling millions of iPhone 4s, Apple has failed to warn and continues to sell this product with no warning to customers that the glass housing is defective.” His iPhone 3GS survived several similar incidents with no damage, so in his mind, the iPhone 4 should, too.
