EXPERT RESPONSE
First of all, let me correct a slight misconception -- any wireless network will only work wherever it provides coverage. Neither Wi-Fi nor cellular are perfect. Both can suffer from gaps in coverage due to limitations in where cells or access points (APs) can be located, as well as the vagaries of radio propagation. But, you are correct -- while the situation is fluid, cellular (be it GSM or CDMA) in general today provides better coverage than a metro-scale or other Wi-Fi network. You can often connect a notebook or other computer to a cellular network via Bluetooth or a USB cable to many cellular handsets; check with your carrier to see if this will work in your case. To avoid the phone altogether, get a PC card adapter from your carrier. You'll need a separate data plan, but this option will enable a notebook to connect to the Internet via the cellular network without using a handset. By the way, if you have a newer notebook computer, ExpressCard versions of these are also starting to appear.
