So, basically you need a laptop upgrade.
When I say ancient I mean two clicks after the stone and chisel. It has a 15 inch screen which is fine but on the low end, bigger is better. My desktop has a 17" screen, when I am at 1280 x 1024 rez, the text is tiny. Blenders tiny text brings my face close to the screen. My friends tell me I glow, from a distance. Got to get a bigger LCD.
K-3D needs a band of pixel gypsies to go crazy making tutorials to explain everything, then one cool project from one primitive to doing various rendering techniques. Building low poly models seems pretty fast, then what?
Wings 3D is better at tugging and pulling than anything else with no boolean functions handy it's kind of labor intensive. I was trying to do a tube hoop, square sides, curved corners. There is no easy way to do this. I would say if you like working that hard go for it. I will tinker with it but the aggravation is very high.
