One of the big issues among us watch geeks that are also tech geeks has been merging our desire to continue to wear our favorite analog watch(es) while simultaneously getting smart watch features. Seems the folks at Kairos had the same concerns and have been hard at work concocting the T-Band - a smart band for your existing watch. They've got three models, one of which even features a OMOLED display right in the band for $179. It's just now beginning its Indiegogo campaign but will fund even if they don't hit their $50k goal (but I'm guessing they will).
