Meet the Raspberry Pi's newly redesigned operating system called PIXEL
Since it's inception, the Raspberry Pi foundation has been solely focusing on improving the hardware experiences of the Raspberry Pi by introducing better and more affordable hardware options. But that's changing today as the guys behind the Raspberry Pi boards are announcing PIXEL which will be replacing the official Raspbian distro that many Raspberry Pi owners opt to use.
Not to be confused with Google's upcoming lineup of Pixel smartphones, PIXEL stands for Pi Improved Xwindows Environment, Lightweight. Deep down, PIXEL is still based off Raspbian and the foundation did not make much changes in the way Raspbian works. But they did give Raspbian a big visual overhaul with PIXEL.
For starters, PIXEL now comes with a splash screen with the Raspberry Pi logo and the interface now has better iconography. In addition to that, PIXEL also comes with several new applications like RealVNC, a SenseHAT emulator and also an improved browsing experience that features improved video playback and an adblocker.
So, if you have a Raspberry Pi board, you can try out Debian Jessie with PIXEL by either updating directly from the terminal or re-flashing via the new downloadable iso file
