User Reviews

  • Although still raw in places, this OS is for sure one of the best things I've seen in the entire internet. Maybe I'll switch to it from Windows 10 when it'll get support for Win7 apps and for NTFS.

  • Interesting project that allows to eliminate Windows in some cases. Though emulation does not embrace all the cases. I hope it will be more perfect. It is already great.

  • Amazing experience the installation, tests and running! I tested some applications: Arduino, Cura, Lazarus and Scribus. There wasn't a deep test, but I have no problems. None problem with this apps.

  • Great project! Let's bring open source to legacy applications. There's no excuse for not going Libre now.
