Indamixx has been loading up mini-laptops with open source audio production software for a while now. I first heard about the company in late 2008. At the time, the company was selling a Sylvania G Meso laptop with an 8.9 inch display, a custom Linux operating system and a whole slew of free and commercial music making tools for creating, mixing, and editing audio.
Now Indamixx has updated both the hardware and software. Instead of a Sylvania G Meso, the new Indamixx laptop is based on the MSI WInd U100. It ships with 2GB of RAM, a 10.2 inch display, a 1.6GHz Intel Atom CPU, and a custom Linux distro called Transmission, which is based on Ubuntu 9.04. It has the latest no-latency kernel which helps with audio production.
It also includes a variety of open source audio software including Ardour, but also some commercial apps like ArdourXchange for importing files from Pro Tools and other Mac and Windows software. You also get 260 plugins and over 350 samples and scratches, plus 30 days of support with the purchase of the $499 laptop.
