I am IT specialist and have to do with all operating systems and from the user perspective, I found (OWN OPINION) Linux users as to unfriendly. Now that I bring with the technical understanding, I have the box set and yet ordered me to tinker. Well, what can I say, my prejudices were unfounded. That is the first product with Linux pre-installed, which works perfectly. I am absolutely thrilled. Although the box needs something, if it comes from the Deep standby or is switched on again via the switch on the back, but this is to get over as a normal stand-by mode is also available, as they are from other receivers knows. The box switches channels to very quickly and also for the laity, the device is very easy to setup and use. The stability is very positive, I could not detect crashes, the functions, the described are available. The processing of the box is also faultless. The positive thing about Linux is the ability to flash other images on the device. In various forums there are images that extend the functionality of the box. Thus, a web interface is very easy to installed separately, which offers the possibility of TV via the WLAN or if desired via the Internet to devices like iPhone, iPad or stream normal PCs / MACs. Even the XBMC Media Center can work with the + signal the VU, so that you can look over the XBMC wonderful TV. I use this solution for example in the bedroom. In the living room the box, connected to a 7.1 system in the master bedroom a XBMC enabled device, which is connected to a small TV. Thus I have saved me embarrassment of long antenna cables and drilling shop. The price of this device is absolutely fine, because you get a lot for it.
