It has a re-designed program launcher optimized for devices will small screens. The launcher uses low resources, is very finger friendly (if you have a touchscreen), and generally just makes the experience of using a netbook that much easier.

That being said, there are some small issues that I have yet to figure out.

First, it is distributed as a .img instead of the universally accepted .iso. This presented me with several difficulties and I am not sure why they chose this much more obscure format.

Secondly, this particular version of Ubuntu REQUIRES a Atom processor. I understand that they made modifications to the kernel to support better power saving techniques in junction with the Atom processor, but seeing as the netbook that I have on hand (HP Mini 2133), uses a VIA processor, that computer is entirely unable to use this version of Ubuntu. Why doesn't it just default to the vanilla kernel if an Atom processor is not available?

I have been perusing Ubuntuforums.org to find an answer to these questions, but as of now, I have yet to find a answer that is more than just pure speculation.

I went ahead and just installed the 8 packages required manually on the hp mini 2133, and the result was...slow. It worked, (with a minor cosmetic issue) but it was very very slow. It took almost 25-30 seconds to change between the different menus. I am guessing this is a result of using it on a machine with a VIA processor, but in the end, I just reverted to the regular Ubuntu desktop.
