Soon you’ll be able to watch the latest episode of CSI on your next trip to London. RCA’s palm-size Lyra Audio Video Jukebox ($399, available this summer) hooks up to your TV and can store and play back 80 hours of programs, movies, or home videos. The 3.5-inch LCD screen is just big enough for easy viewing and still small enough to go almost anywhere. The 20GB hard disk can also store hundreds of hours of MP3 music or 100,000 digital photos.
