Few people probably saw this one coming. Microsoft Windows has long faced off with Mac OS X on the desktop, and while only a distinct minority adopted Apple's platform, the conflict has captured the interest of the tech industry for years. Open source advocates have even entertained the idea that Linux desktops would one day topple Microsoft's empire. Far fewer people speculated that it would be a mobile operating system that would start to replace Windows on desktop machines. Yet we've already seen Acer move in this direction, and now HP is doing the same. Today HP announced the Slate 21 AIO, a 21.5-inch tablet that wants to sit not on your lap, but on your desk.

The HP Slate 21 sports a kickstand in the back that will position your tablet at the same angle as your aging all-in-one desktop PC, but it can be repositioned to various other angles that may be more finger or stylus friendly. Judging by the provided images, multiple USB ports in the back can handle your keyboards and mice, though I would imagine Bluetooth hardware will be supported as well. The computer - erm, tablet - will ship with a Nvidia Tegra 4 processor and run Android 4.2.2.

The Android interface has no problem scaling to larger screen sizes, but the vast majority of apps look atrocious when stretched too far away from their native mobile dimensions. Nevertheless, an Android desktop may be a good fit for a generation of people raised using smartphones and tablets, not heavy desktop interfaces, to do the bulk of their computing. It could also be just the ticket for the leagues of people who never quite grasped the complexities of Windows but still want to search the interweb, browse the YouTubes, and send tweets just like everyone else.

PALO ALTO, Calif., June 24, 2013 – HP today unveiled the HP Slate21 All-in-One, the company’s first All-in-One PC built with the AndroidTM 4.2 operating system. The HP Slate21 All-in-One enables families to enjoy cloud-based entertainment features such as TV streaming and Android apps.
The HP Slate21 All-in-One expands upon HP’s portfolio of multi-OS products and is ideal for family activities, providing easy access to entertainment and productivity features, plus fun Android apps.

Full HD touchscreen, high-quality graphics, and sound improve user experience

    For a whole desktop contraption like that, I would expect it to be x86-based so I can get Windows 7/Ubuntu on it as well.

      They both run on ARM too. At least Ubuntu/Linux does.

      • Hal Motley

        Ubuntu is more forgivable (though I can imagine A LOT of tarball installations, which I am not too keen on), but most Windows programs will be closed-source and require the developer(s) to compile ARM binaries.

        Also Windows 8 RT is the only true "ARM version" of Windows for support.

    As a real computer, I'd prefer a Windows machine. If I were to invest in something like this, I'd expect it to get Android updates in a timely manner. I'd also like the option to install Windows. I'm sure this will cost a decent amount, so I'd like to do more than just run Android on it. As an Android machine though, this is pretty cool!

    One of the dumbest ideas I've ever seen... It's like replacing all of your computers with iPads...

    • John O’Connor

      Still much cheaper than an iPad

  • varun

    How depressing. The major thing that Android is missing that would make it totally usable on a device like this is a windowing system. Guess who owned one of the smoothest windowing systems around in the form of WebOS?

    Lets hope the rumours of KLP being Laptop / Desktop friendly are true then.....

  • Aaron Jaeger

    If this thing was launching with a more desktop friendly Android 5.0 or even Chrome OS, I might jump on it. As it stands, I'm not sure it will work.

    • Sergio

      I hope, desire, cry and pray for Android 5.0 being optimized for desktop

  • mauric

    Just give me the 8mm thick version and i'm sold.

  • GigiAUT

    Lose 11 inches, the mouse, and the kickstand and we can talk about it.

  • Matthew Fry

    Huh. Was expecting it to have a desktop OS somewhere in there.

  • Guest

    Well, HP tablet users are well accustomed to dual booting between OS's... Just this time it will be Windows/Android and not WebOS/Android :)

  • Iggies

    I know I don't speak for anyone except myself, but the only two things I need a PC for right now are torrenting (I don't like torrenting over Android due to privacy concerns) and having a device to stream all of my content to my Roku via Plex. I can accomplish these two things on a Windows, Linux or Mac device. I am hoping I'll be able to do it on Android in the near future, but we're not there yet.

    Ladies and gentlemen. Remember Star Trek, Star Wars, Avatar, and so on ? The hand-held computer is the future. All-in-monitor. Apple was right. Touch screen is. While we will never shed our love of powerful tower pc's, in the end what we need is a powerful, touch screen, waterproof tablet that does all we need and we can use it on the desk, in the lap, in the bed, carry it in a backpack and deploy anywhere. Slate21 is only the beginning. With ever-improving microLED technology and better polymers, we will soon see the interface from Avatar on the open market.

    This is exactly what I was looking for. We have been watching shows on the laptop and no longer use the TV. There are some cool Android Mini PCs that plug into the TV HDMI port, but I'd have to buy a TV to use it. A 21 inch tablet could run Netflix, Hulu and various other video sources. There even are flavors of Torrent, if one had to download the videos.

    Now I just need to be on the lookout for a deal
