I threw Ubuntu 12.10 Beta onto my lowly Acer Aspire One netbook (D255 1GB RAM), I fully expected to change the desktop environment soon after install as my first install some time back with Unity was unusably slow. Not so with this version, for web surfing and the odd bit of document editing its great. The Dashboard opens quickly. I was somewhat worried after reading about the dropping of Unity 2D.

A step in the right direction for me. Will see how it pans out when my new development laptop arrives later in the week
