The little display is nothing fancy, you'll have to build a housing for it BTW and a longer cable. Turned out to be a PITA finding a PS2 keyboard to use with it. LOL! Anyway, if the budget allows it's fun but it's not necessary strictly speaking since it does not completely eliminate the need to use a computer. It just displays decoded packets and lets you send APRS messages with the keyboard, so basic functionality.

"Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty. Nobody is able to achieve this completely, but the striving for such achievement is in itself a part of the liberation and a foundation for inner security. " --Albert Einstein
