There's both bad and good in the fingernail size of the "Mogo Dapter": It could easily get lost (bad), but it's so small that you may never need to unplug it (good). The Lilliputian Bluetooth adapter is tinier than any USB storage key we've seen, yet the Red Ferret says it promises to provide faster connections and enhanced multimedia quality. Just be careful with it around toddlers, especially at Halloween--it could be mistaken for a half-eaten peanut butter cup.
