It's my understanding that they've known the folks at Bantam for some time now, and that given how hard it can be to run a physical product company (especially one that does some in-house manufacturing for your own products!) in the bay area, that they're looking forward to having such niceties as 'pto'.
They're really excellent people, and made a huge difference to me when I first moved to the bay area, so while it's sad to see them leave, I understand it, and hope this leads to a better situation all around for them.
