This item is for the convenience of field support and sales.
Someone like Jane Barth or Tari Runyan needs to hookup an AV-TS unit to her laptop to create a database on a floppy disk. There is a perfectly convenient floppy drive on her laptop already. These old AV-TS units exist in the field today and they will exist in the field tomorrow. The company is not going to eat that inventory.
Until the new unit becomes available for demonstrations and production, sales continues to demo the concept of touch screen voting with the old unit. They can't even demonstrate the uploading of results unless they have an AV-TS unit connected to their laptops.
For versatility's sake with the new unit, you should consider having the ability to download/upload a flash RAM on a GEMS computer.
