H J,
Hate to be a contrarian here, but I must disagree with most of the folks above. I'm holding petinsurance.mobi, propertyinsurance.mobi, condoinsurance.mobi (among others), and I've already had several nibbles... I think insurance-related .mobis will do well if .mobi takes off generally. [This being said, the (mis) spelling is a major disadvantage, but you never know what might happen ... ]
