Never let it be said that I don’t listen to readers. In April, after I favorably reviewed a wireless product that elegantly displayed baseball scores, Don wrote: “How could you recommend that, especially at the price of $200 for a unitasker? This isn’t worth $20 for what it does. What a joke. Please check out Chumby for a slightly cheaper and much more functional alternative.” I’ll stand by my review of the graceful Liveboard. But Don, despite his manners, had a point: It does one thing in an era when we expect our gadgets to be multitaskers.
