You are an exception. Very, very few coders travel by plane that much.

Local work is not a unique property of DVCSes. (See shelving /
checkpointing planned features in SVN 1.8).

This is a very good point. Though it is still a specific need. The VCS is
here to help the team. If individuals want to play on their own, it's only
"nice to have" IMHO and shouldn't make the other part of the process more
complex.

One could argue that it takes a bug in SVN to get stuff out of sync while
it only requires a user error in git, but yes that's a valid argument. Not
as strong as you say because whether you have a SVN or git repos it would
be very stupid not to have automatic backups for it. I'd be happy to see
more details on that point.
