Yeah I find that a lot of FOS software is missing some features compared to commercial software. But many times after the initial learning curve it's really not missing as many features as I thought. For example OM has a super easy way to record a track, which GM doesn't have, and I now use it often for new hikes so I can find them again.
FOSS represents a world I would much rather live in, I think it's a more equal world, so some minor inconveniences and even donating small bits of time and money to help the project succeed is a feature that is important to me.
