I dig this DIY slider, too, and I wonder what's the best approach to make the kind of camera platform that is similar to Dana Dolly's. The wheels swivel on the Dana Dolly, which makes it better to use for curved tracks.

The biggest reason why I think they'll be great optically is because Matthew Duclos helped designed the lens. If you don't know who he is, look up Duclos Lenses, or talk to anyone who operates/own cinema cameras and cinema lenses.

He's definitely highly respected.

Honestly, if you're already comfortable with the windows OS, stick with it and get the laptop that I have and use for video editing on Premiere, the Gigabyte P35W v2. It just spanks the Macbook Pro Retina with its performance:

It's about the same size, thickness, and weight as the MBPR, but can hold 4 hard drives!! Plus, not only does it have the Intel i7-4700HQ Haswell, but it has a whopping 6GB nVidia Geforce GTX 870M with 1344 CUDA cores.

Add to it a 1080P IPS screen, 16GB RAM, and 4K-ready miniDisplayPort, and you have a real performance powerhouse in a lightweight package.
