Tabular model: Not ready for prime time?

While the tabular model in SSAS makes it much easier to build cubes than the multidimensional model, I am not seeing it used as much as I expected. One reason is if you are a BI developer and have been using the multidimensional model for a while, you tend to stick with the tool that you are most familiar. You will need a compelling reason to learn a new tool and make the switch, and with the tabular model being a "version 1? with some missing features, there is little incentive to make the change.
