The only software generally comes from the community, other than the OS itself. There's just too small of a market unless you see things as a "labor of love". It is getting better as a whole, however. There is generally a solution/program that will do most of what you need.
Software availability has always been an issue for OS4 machines, and the issue will remain the same regardless of whether it's a lowly SAM 440 like I have or a powerhouse like the SAM 460 or X1000.
