First, quit being pretentious, you're no good at it.
The FEATURE that was linked, not a plan, is the tethering package that Verizon Wireless offers for any eligible phones, including feature phones. It is an additional cost over any other data packages that might be in place (required or not). While there might be methods of using your Android device as a tethered modem they are not supported and if you were to spend as much time reading as you do writing you would discover that doing so violates the Terms of Service and makes your account subject to action such as suspension or even termination at VZW's discretion.
That said: The $29.99 E-Mail & Web for Smartphones feature is the one that virtually everyone getting a DROID or non-Blackberry smartphone will want, and it's the minimum required. For Blackberries if you will be connecting with a Blackberry Enterprise Server there is a requirement that you use the $44.99 per month Blackberry Unlimited feature.
The $29.99/mo feature is unlimited usage of internet connectivity with no hard/soft caps on how much data is consumed but you are governed by terms of service on what you can do with that internet connection.
If you are using your device as a tethered modem, legitimately, there is a 5GB/mo soft cap on its use in that manner with overage charges applying after the 5GB limit is reached. This is completely separate from normal usage of the device by itself which remains unlimited.
