Clark has long coveted the iPhone, but he's too cheap to get one. Recently, his wife has been hinting that she'd like one as a present.

But Clark may be able to stave off his wife's iPhone fever thanks to a new website called Kinoma.com. If you have a Palm-based or Windows-based phone, you can use Kinoma's software -- for a onetime fee of $29 -- to enjoy video, audio and pictures on your handset. Kinoma can simulate an iPhone-like user experience on a non-iPhone device.

Cellular technology is advancing so fast that your mobile phone may soon replace your wallet. Clark thinks that within 12 month, we'll begin using our cells to pay for things here in the United States.

It's already the preferred way to buy at vending machines in Japan. In Africa, meanwhile, cells are used to pay for everything via text messaging. In fact, many African currencies are so unstable that people transfer minutes as currency instead!
