The current advantages of BIM and Revit in particular are threefold. BIM software allows for the design and delivery of a better product for owners, more cheaply, and more quickly than was otherwise possible.
Projects designed using BIM software are by and large likely to be of a higher quality as they are checked for efficiency by computers, which are less prone to overlook small details even when reviewing changes at 4:00 on a Friday evening. Furthermore, it reduces the amount of bickering for space that previously came with interactions between different disciplines of engineers and architects. This benefits owners as they will receive a final product that is more efficient and of a higher quality.
BIM software also loans itself to saving money on both the design and construction ends. Disagreements between design can be solved efficiently in minutes instead of days which leads to fewer design professionals being needed to complete the design for a project. This would result in design firms and thus owners saving money on the project.
Time is also saved when BIM technologies are implemented into the design of a building. Instead of communicating by the postal service, fax, or email as Fiori said was done in the past, a superintendent can circle something on an Ipad while he stands right in front of it and have an answer from a designer faster. Also, since all of the details of a building are contained in a single model, and all drawings are derivative of said model, disputes for space can be solved more quickly, if not automatically. Furthermore, the creation of a single model and the process of pulling different plans, sections, and 3D renderings from the model is much quicker and more accurate than the individual creation of each drawing in AutoCAD and using a separate software to create a 3D rendering.

I agree that Revit saves drafters a lot of time and energy when compared to AutoCAD. I think this is primarily due to its ability to create sections, perspective renderings, and various plans, all from one one Revit model. Furthermore, Revit, and other Bim Software promotes cooperation between different design disciplines with file sharing and inconsistency detection.

I agree with your sentiment that Revit and other BIM software will likely take a while to catch on and become widely used in the construction and design industries. However, I would like to point out that owners and developers, who pay for design and construction projects are the ultimate arbiters of what will and will not be used in the industry. I believe the benefits of BIM software will push these stakeholders to require the use of BIM for their projects. As a result, i predict the rate at which firms will adopt the use of these kinds of programs will increase. Just as Fiori said, contractors exist to make money and leaving jobs on the table for lack of technical expertise is the same as leaving money on the table.
Mika,
I agree that Revit comes with a learning curve and thus is likely to dissuade many companies from pursuing its use. Like you and Fiori said, this fact is compounded by a lack of formal training as users are often expected to learn the ins and outs of the software on their own. I do however feel that the industry will require more and more companies to switch to BIM as time goes on as it helps designers and constructors deliver a better product, faster and more cheaply. It is for this reason that i believe owners and developers will begin to require the use of BIM on their projects.
