It's taking me 1 hour to download on my DSL...

Something of that size just does not usually bode well for it being very usable on lower end machines.

Looking at some of the discussions on their group, it sounds like probably one big chunk of the download size is having the .NET framework included with it - that doesn't really have anything to do specifically with direct modeling, it's more likely to have to do with their choice of what system to base the UI off of.

I've worked very hard to avoid this kind of bloat with my own software, so every time I see it, it just is a kind of ugly thing to me, personally... ;)

For me increasing installer size by just 5MB is a big deal that I treat seriously, MoI v3 is going to have some kind of increase in size like that.
