It seems Android-powered all-in-ones are set to be all the rage this year, with new offerings already announced by LG, Acer, and Lenovo. And now HP has thrown its hat into the ring with the Slate 21 Pro, a slightly enhanced version of last year’s original Slate 21 that’s aimed at business users.

Not only is it an Android-powered PC all by itself, but its HDMI connection allows it to also act as a monitor for other Macs and PCs.

The most noticeable difference between the original Slate 21 and the new Slate 21 Pro is the color; the business model comes in a slightly boring black while the original is completely white. But of course, that’s not all there is to it. The Pro model also boasts upgraded internals.

It’s powered by a quad-core NVIDIA Tegra 4 processor and 2GB of RAM, with 16GB of internal storage. Its 21-inch IPS touchscreen sports a full 1080p resolution, and there’s a front-facing webcam that’ll shoot 720p video. The Slate 21 Pro also offers three USB 2.0 ports, Ethernet, a headphone jack, and Bluetooth 4.0.

It also boasts an HDMI port, which lets it act as a minor for other machines, or even allows you to hook up a games console or media player. There’s a USB 2.0 upstream port as well that allows you to use the Slate 21’s touchscreen capabilities on a Windows PC.

The Slate 21 Pro ships with Android 4.3 Jelly Bean pre-installed, and it’s available now from $399.
