They have at least one or two USB ports, and some have a FireWire® port, but most don’t have enough places to plug in all your peripherals. Everybody’s got gadgets with USB or FireWire connectors—iPod® mobile digital devices, DV camcorders, digital cameras, external drives, printers, keyboards, mice, scanners, to name a few—wouldn’t it be nice to plug in more than one at a time?
