wow, i didnt realize that it still doesnt have a modeling system after all these years. I saw it when it first came out for LW. the concept was nice as a plug-in for bypassing LW's craptacular character animation system, but as a stand-alone it was always an iffy proposition.
I don't know that I would recommend it for absolute beginners to 3d, the interface always struck me as a bit convoluted(too many expando-tree hierarchies). Those that bought in on this, understand the point was to build a user-base and you will likely be spending a great deal of time on their user forums asking questions to figure out how to just the basic stuff.
For those that didnt bite, I think there are still free student/demo versions of Maya and XSI that arent just 30 day trials(like 3DSmax). The versions are crippled(restricted on certain limits: polygon count, particle generators, frame count) and use non standard file formats and watermarks on renders to keep you from using them for commercial work, but if all you want to do is dabble then it might be a better starting point.
As a rule: any 3d package that doesnt detect where the cursor is hovering and autoswitch priority to that viewport is not a true "professional" package. If you have to click on a viewport window and then click again to pan/orbit/zoom, it is a very poor piece of software.
