sezyboy, if you think Canada has it hard on the technology front than you should come and live in your home country's technologically retarded cousin, Australia. At least the U.S. is just south of the border, whereas Australia is stuck somewhere between the Pacific and Atlantic Ocean's. A 2megapixel camera phone over here is the shit and we are only just starting to get phones with hard drives onto the market (well, sometime this year).
punkouter, you forgot to add the Samsung SCH-V770, a 7megapixel phone with "manual focus, shutter priority, AE lock and an optical zoom as well as MP3 functionality and a business card reader." It was launched at CeBit 2005 (10th March).
I've also heard of facial recognition being built into Japanese phones as a security feature.
I can't say I share bgerber's view that cash will be replaced anytime soon; weren't credit cards supposed to replace cash by now? Cash is too convenient, attracts 0% interest (unless you are borrowing it), and, as the saying goes "money talks".
