The HP Slate 21 is a computer developed by Hewlett-Packard that runs the Android operating system. It was announced on June 24, 2013, via HP's blog The Next Bench with a price of $399.00, and released in September that year. It is described as either an all-in-one desktop computer or a large tablet computer.[1]
The device uses a 21.5-inch touchscreen and a Tegra 4 processor, but does not include a battery. It runs Android Jelly Bean as its operating system. It received mixed reviews from critics, with reviewers favoring the screen's wide viewing angles and Full HD resolution, while criticizing the lack of software optimization for the large display.
Hardware and design
The Slate 21 uses an Nvidia Tegra 4 system-on-chip running at 1.66 GHz.[2]: 2 It includes 1 GB of DDR3 memory and 8 GB of internal flash storage, which can be expanded via an SD card slot.[3] Connectivity support includes three USB 2.0 ports, a 10/100Mbit/s Ethernet socket, a 3.5 mm headphone jack, Bluetooth 3.0, and dual-band 802.11 n Wi-Fi.[4]: 1
The Slate 21 uses a 21.5-inch IPS panel with a resolution of 1920×1080.[2] The device includes a 2.1 megapixel front-facing camera capable of recording 720p video. It does not include an accelerometer, which meant that any Android games which use accelerometer controls cannot be played. The screen has a glossy surface.[2] It is an optical touchscreen supporting two-point multi-touch via three cameras, unlike other tablets which use a capacitive touchscreen.[4]: 1 The device uses a white plastic chassis, with an easel-like stand on the rear which allows adjusting the angle of its tilt between 15 and 70 degrees.[3] The device can be fixed to a wall using a VESA mount if the hinge is unscrewed.[4]: 1
A USB keyboard and mouse is bundled with the device. The keyboard includes shortcut keys for access to Android menus such as the home screen and music controls, replacing the usual function keys and Start/Escape keys.[2]: 1 It does not contain an internal battery, requiring users to turn off the device when moving it between power sockets.[4]: 3
Software
The Slate 21 runs Android 4.2.2 Jelly Bean. Software bundled with the device include Google Chrome, HP's own media playback app, and the mobile version of Kingsoft Office.[3]
