There are two models of Echo smartpen:
The smartpens can be purchased individually or as part of a bundle.
What is the difference between the 2gb and the 8gb Echo?
The two smartpens are identical in every way except for the volume of storage.
There is a difference in price. Why would you choose the 2gb or the 8gb model?
The 2gb Echo is shipped is a new-sealed box and includes some items that are NOT included with the 8gb, specifically a starter notebook and an extra ink cartridge.
The 8gb Echo is NOT packaged in a sealed box. It is new, with a full warranty from Livescribe, but the item is shipped in a plain brown box in the way that they are currently shipped from Livescribe.
While the price difference is modest, very few customers will ever need all the storage in a 2gb Echo. For most customers, the extra memory will (literally) never be used. Unless you intend to record a great deal of audio (as a judge may do, for example, recording many many hours of testimony), the 2gb Echo is likely sufficient. Use the extra dollars to buy something "useful" such as Livescribe paper products or ink cartridges.
