Am I missing something here? Why would I pay $399 for this "new" IDE, when the existing competing products are either free (Radrails & Netbeans) or cost about 1/5th as much (Textmate) ?
Like they say, no one ever got fired for buying IBM.
It's expensive because it's aimed at accounting drones who make the decisions about what to buy and who want software from a "big name" company like Borland.
On a related note, there is at least one other similarly expensive rails IDE, but the name escapes me right now.
