A good thing about HanDBase is that it can work with its own desktop version for Windows (and desktop HB works well in WINE for Linux). There is apparently a Mac desktop version, too.
So it's easy to swap db files b/w all devices. When I was going back and forth b/w PortaBase and HanDBase, I made a *.bat file that could convert en masse .csv files to HB files.
If someone needs that converter, pm me.
HB support has always been great. The developers gave me keys to a free-of-charge beta Symbian HB, never released, but it worked flawlessly on my Nokia E7.
