I've been using TomTom Home for about a couple of years. The earliest iterations were awful, but each succeeding one gets better. The present one, in common with its recent predecessors, is well thought out, works well and causes no problems. It took a long time but TomTom has finally produced a usable program, so congratulations to them. The program doesn't have the look and feel of a Mac program (I assume it's a port from the PC version) so it lacks a certain elegance, but otherwise it's fine.
