What I want to know is the PC that they are using. I love to use Linux on my computers but always have a hard time making sure that the hardware is completely compatible. I hope such adoptions lead to better hardware compatibility with cheaper commodity hardware. I've had a few weird experiences: 1. Previous laptop: wifi under Linux didn't connect to certain networks, wile the same machine connected to all networks under windows. 2. Current desktop: Under Linux, it will sometimes freeze with no errors reported (usually under heavy and sustained CPU and graphics usage) but nothing of the sort happens under windows. And these issues are really hard to figure out for non systems programmers like me.

A government agency can always select hardware with good Linux compatibility.

presumably the police are not using a GPU, which seems to be a major source of issues in our lab. 64 bit ubuntu gives me more hardware headaches than 32 bit for things like wifi. Again this is for police desktops so probably they don;t use wifi.

  The less frills and peripherals the better, I guess. Although I've usually seen most cheap desktops come with some entry level video card, so I doubt they have none at all.

1) WiFi chipset manufacturers and the linux kernel are and have been at odds for some time. The issue is primarily that some (many?) of the chipset manufacturers that make the machinery that runs WiFi cards don't provide open source drivers for their chipsets. Some of these make proprietary kernel-compatible drivers (often inferior to their Windows offerings), and others have to make do with hackish workarounds (NDISwrapper). I'd argue this isn't a problem with Linux as much as it is the device manufacturers. I'd also argue from the end-user perspective that doesn't matter much. 2. See (1)--there is a notorious hate-hate relationship between nVidia and Linux; I'd bet that what you've experienced is related to that, although happily will admit to being wrong (if you aren't engaged in accidental selective memory--that is, remembering times Linux froze but not Windows, even though the latter surely has frozen on you before, under similar circumstances).

  You're right, the Wifi chipsets have proprietary driver issues. My graphics card is one of those low end ATI models that come in cheap desktops. I've heard that graphics cards can be an issue. I wonder if I could just disable the graphics card in some Ubuntu setting. I just want to run things like vi, ssh, gcc and a browser most of the time anyway.

    Heck, I've got a fairly decent graphics card in this not-so-cheap laptop (that's what I hear anyways; it's an Nvidia Quadro K2000m in a Thinkpad W530) and it has problems. Apparently that's due to the Optimus "stuff", though. Fortunately, like you, 95% of my time is spent using Firefox, a terminal, SSH, and mutt, so I don't need the higher graphics capabilities. (Although occasionally it might be nice to watch a movie at higher quality on a long flight, though.)

    Intel integrated graphics are getting astonishingly better, and they're open source friendly, except for the Atoms that have the pathetic PowerVR graphics. At this point, for casual use, I don't think it's worth the hassle dealing with AMD or NVIDIA graphics. Though, if you are burdened with having to run a video card in Linux, then AMD models have basic performance for less hassle than NVIDIA. You actually can disable the graphics card, but you probably don't want to, because you would have no bitmap graphics at all. Vi, SSH, and GCC don't depend on graphics, but a browser does.

  It doesn't matter if it's NVidia's fault or the WiFi chipset manufacturer's fault that Linux doesn't work well out of box on OPs computer. I've had similar experiences with Linux, and all I cared about was that I didn't want to spend several hours figuring out why some graphics problem prevented my laptop from booting, or why I couldn't connect to WiFi. Accusing OP of "accidental selective memory" when he points out that his computer freezes frequently running Linux doesn't help. Problems like this make Linux unusable compared to Windows for new-to-Linux users who are willing to try it out. That makes it a Linux problem, which Linux needs to figure out how to solve- whether that be improving their poor relationships with WiFi manufacturers or improving drivers.
