Smart phones are a combination of a cell phone and PDA functions all in one device and are much bigger and notably more expensive than regular handsets, generally costing in the neighborhood of $600. However, one wont need to carry around two separate units.

Most individuals who would need a smart phone are people who are out of the office for long periods of time that require connectivity to e-mail and appointments. While the regular individual can get by with a basic cell phone or if you already have a separate PDA device and dont wish to incur the additional expense of combining the two features into a smart phone.

If you are thinking about purchasing a smart phone, you will need to consider finding a cell phone plan that can provide the additional data for e-mail and for Internet browsing. For example, some cellular phone providers charge a flat fee for the megabyte usage while other cellular phone providers furnish a monthly allowance for megabyte usage. Finally, if your smart phone comes with Wi-Fi access, see if you cellular phone provider offers Wi-Fi plans.

Now you have the scoop. So what it really boils down to is the PDA functions. If you need to be connected to the internet and need email capability, its worth checking out. But for most of us, a regular cellular phone should meet our needs quite nicely.
