The Landel Mailbug is a portable email terminal created and developed by Landel Inc.
The device has a full-size QWERTY keyboard and a 6-line by 79-column text-only LCD display. It connects to a standard POTS telephone line and checks for new incoming mail or delivers outgoing mail by periodically calling into Landel's proprietary service.
Mailbug is an embedded system, not a computer, and has no ability to display non-text e-mail attachments, such as spreadsheets or images (although it does attempt to extract the text from PDF attachments). As a result it is thought to be completely immune to traditional computer viruses.
Mailbug is primarily marketed towards people who do not want or need a computer, especially seniors.
