Chromebooks are laptops running on Google's browser-based, cloud-focused Chrome OS. Sumsung Chromebook is a lightweight, thin, and cheap laptop suitable for those who need a powerful browser.
Chromebook features include an SD card slot and combination microphone-headphone jack. On the back are a USB 2.0 port, a USB 3.0 port (a first for a Chromebook), and an HDMI 1.4 port. A USB dongle for Ethernet is included if you can't or don't want to use the 802.11n Wi-Fi. A Webcam perches above the screen. A 16GB of flash memory, but with ordinary amounts of videos, music, photos, and letters one is likely to rely on Google Drive for some storage.
