I've tried it twice now, and hated it both times. I was very excited about the prospect of a still-actively developed "Textmate" that would run on my other development machines. (I've got four active development machines, and only one of them is a Mac.)
In practice, though, it just felt wrong to me. It doesn't look as nice; I couldn't easily figure out keyboard / menu shortcuts for a number of my bread-and-butter Textmate activities; and I was unable to figure out how to manually install bundles.
Perhaps I just haven't given it enough time, but it always feels like it would be easier to just share my source directories so I can edit them from the Mac using Textmate...
