Easy payments through cell phones combined with ubiquitous, cheap phones combined with cell-phone interfaces to buy/sell/access everything (stocks, insurance, micropayment): this is a powerful change in the way people work and do everything. But I think the step after the phone is going to be even more interesting. Its about the point now where any device can be hooked up to 3G and have a touchscreen interface (basically having a touchscreen phone embedded in the device, with software tailored to the interactions the device can make with other devices, or suppliers, or support, etc)
