Handspring Visor
PalmPilot’s wild child. Came with more add-ons than a Happy Meal and just as much confusion.

Quick Bits
What It Was
The Handspring Visor was a Palm-style PDA with more personality and a slot for wild little Springboard modules. In theory, you could turn it into whatever gadget your inner mall-kiosk futurist wanted next.
Why It Mattered
It captured a moment when mobile gadgets still felt gloriously unfinished. Instead of locking you into one job, the Visor suggested your organizer could become a camera, MP3 player, modem, or GPS machine if you bought enough weird extras.
Why It Did Not Win
Expandable ecosystems sound amazing right up until people realize they would rather not carry a pocketful of attachments.
Once phones and handhelds started packing features in directly, the Visor's modular charm stopped looking like the future and started looking like a fun detour.
