Buried in the world of tech news yesterday was the announcement of the acquisition of Motorola subsidiary Starfish by Pumatech. Most notably, this deal brings together the makers of IntelliSync and TrueSync, two software products that synchronize data between computers. Less notably, this deal reminded me that I once owned a Rolodex REX device. Designed by Starfish and manufactured by Citizen (the watch people), the REX was marketed by Franklin, and eventually sold to Xircom who discontinued it in 2001. The tiny size of the REX was wonderful. It took up no space, and held all the data I really needed to take with me. To sync it, I just stuck the entire thing into my laptop’s PC Card slot. Small and convenient. Too bad I couldn’t stick it into my cell phone too.
