NFiDB is an attempt to steal back some of our freedom and allow the device to be used how we see fit.
It will make your iPad useful into the future, even if it is just as a backup drawing tablet.
The major impetus was to be able to draw on my laptop using Rebelle and Krita without needing to haul around an extra graphics tablet while I traveled.
Let this be just the first of future tools that allow us to actually use the wonderful hardware we purchased in the way we want to use it—without subscriptions.
