HP Pro Slate 12

HP is back with a pair of new Android tablets geared towards businesses. The HP Pro Slate 8 and Pro Slate 12 bring a 4:3 aspect ratio that's more like standard paper sizes than the 16:9 tablets we're used to, and unlike some of HP's previous Android offerings, these two aren't terribly underpowered with a 2.3GHz quad-core Qualcomm Snapdragon 800 processor (which while a year old at this point, isn't a bad chip to have running things). And both measure just 8mm thick.

The crazy thing is the sheer size of the Pro Slate 12, which offers a huge 12.3-inch display. Alas, that screen is a 1600x1200 number, so while it's close to HD, it's still a disappointment compared to comparably-sized tablets out there.

Weirdly, the Pro Slate 8's 7.9-inch screen has a resolution of 2048x1536 — exactly the same as the 7.9-inch iPad Mini. Yes, the little one has a markedly better screen, at least in terms of raw pixel count and severely so when measuring pixel density (163ppi on the Pro Slate 12 and 326ppi on the Pro Slate 8). Both are at least topped with the new Gorilla Glass 4 and sport dual front-facing speakers.

HP Pro Slate 8 with Duet Pen

The weirdest part is definitely the pen, the "Duet Pen". The pen here supports both on-screen and ink-on-paper writing/drawing/what-have-you, and with the HP Paper Folio case you can literally write on a piece of paper and have that data transferred over to the tablet. How? With an array of four microphones on the tablet that pick up the super-high-pitched sounds emitted by ultrasonic emitters built into the pen. Qualcomm's been showing off the technology for years, and HP's tablets are the first to actually implement it.

If you're so interested, both tablets are available now from HP (though neither has yet appeared in their online store), with the Pro Slate 8 clocking in at $449 while the Pro Slate 12 is $569.
