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.

Lenovo has today kicked off its CES announcements with the unveiling of its first Android-powered all-in-one PC. It’s called the N308, and it boasts a 19.5-inch HD+ display with a 1600×900 resolution, a quad-core NVIDIA Tegra 4 processor, and up to 500GB of internal storage.

Alongside its new Android-powered tablets and Liquid Z5 smartphone, Acer today announced the TA272, an all-in-one PC that runs Android 4.2 Jelly Bean on a 27-inch WQHD display. It’s powered by a quad-core NVIDIA Tegra processor that promises to fulfill all your gaming and home entertainment needs, with front-facing Dolby surround sound speakers built-in.

Acer has today announced two new Android-powered tablets that it will introduce at CES in Las Vegas next week, one of which is a $180 iPad mini clone. It’s called the Iconia A1-830 and it sports a “premium aluminum” chassis that houses a 7.9-inch display, a 1.6GHz Intel Atom processor, and 1GB of RAM.

Acer also announced the Iconia B1-720, an entry-level device with a $129 price tag that looks a lot like the 2012 Nexus 7, and has a 7-inch display and a 1.3GHz dual-core processor.

The Android 4.3 Jelly Bean update for the HTC EVO 4G has been delayed until mid-February. The software was initially expected to make its debut at the end of 2013, but HTC America president Jason Mackenzie today confirmed on Twitter that users will have to wait another few weeks for it.
