UNR is basically a custom version of Ubuntu Linux designed for low-power laptops with small screens and Intel Atom CPUs. At its core, it’s pretty much the same operating system as the full blown desktop version of Ubuntu, but comes with a nifty program launcher optimized for small screens. And it features some CPU customizations to take advantage of the Intel Atom’s power-saving features.

I was actually pretty surprised to hear about the proposed 5-10 second boot time. But while I was skeptical, I was also optimistic. It turns out that Carr had misunderstood some data, and while Canonical is working to improve the boot time, there’s pretty much no chance the developers will be able to bring it down to under 10 seconds.
