Samsung's seven Book 9 models all offer roughly the same array of inputs and outputs (pictured), with just some slight variations on the media card readers. All come with one each USB 3.0 and USB 2.0 with sleep charge, microphone/headphone combo jack, multi-card reader (3- or 4-in-one, depending on model), and Gigabit Ethernet port (with required adapter). There's also a VGA and Micro HDMI ports, both of which require an optional adapter. Samsung also packs a pair of 1.5-watt speakers, internal mic and HD webcam.
Apple no longer bothers with USB 2.0. The MacBook Air includes two USB 3.0 and a Mini DisplayPort/Thunderbolt port for connecting to external monitors, storage devices and networking. There's also a SDXC card slot, stereo speakers, a 720p FaceTime HD camera dual mics a headphone port and support for the iPhone headset with remote and mic. Both company's ultraportables feature a backlit keyboard and large touchpad with support for multi-finger gestures.
