Ruby on Rails sounds very nice, but many of the parts sound very much like WebObjects and Enterprise Objects. Other than the obviously distinct features (Prototype, for example), how does Rails stack up against WebObjects and Enterprise Objects, which has been around for a decade, and four(?) years in it's current Java incarnation? Especially now that WebObjects is freely included in Apple's developer tools. I've tried Googling on this topic, and lots of people want to know the difference, but it seems the closest thing out there is a description of how to migrate from one to the other. It would be really great if O'Reilly could do a side by side comparison of the two.
