Tardberry is very similar to the definition of an itard.

When someone has purchased a device because its the 'in thing' or they have friends who have one and have no clue how to use the device or what it actually does.

Slight snipe on the term retard except the only excuse for being a Tardberry is of actual ignorance and natural born stupidity
Someone with a zero IQ with a blackberry who clearly is incapable of helping themselves or learning anything via trial and error.

Someone who buys the device without actually knowing what it is or how to use it, normally struggles with reading and writing as well

One of the prime examples of a Tardberry is a wanna be gangster as they like the instant messaging ability and keyboard for fast 'kill' or 'pizza order' requests to mummykins
