This laptop has as standard a Linux distribution. If you want to use it with RISC OS you must join the funding of the RK3399 RISC OS adoption from our Kickstarter campaign.
The RK3399 RISC OS image includes the Cloverleaf RISC OS Standard Distro and incudes many powerful applications. There is also option for the Plus and Art Distro.
The development of the RK3399 RISC OS image for the PineBook Pro will still take 6 to 9 month.
The laptops are only available in limited numbers and only produced in batches every 4 to 6 month. Currently they are avaiable (May 2021) but can be sold out any time.
