Truespace was my baptism to 3d. I used versions 1, 2 and 3 and I found it nice to use. But the more I learned, the more I found the limitations of Truespace to be a problem. I tried a demo of 4, and I thought it was moving forward too slowly, and not addressing fundamental workflow issues. I'm not a big fan of keyboard shortcuts, and it was becoming the only way to make anything in Truespace without it taking three months.
I agree entirely about the packs. It's a slippery slope.
