GNOME 2.16 Beta has been in Edgy Eft (Ubuntu 6.10) for the past few days [or even a week or so]. It is functioning extremely well.
Read the overview here
As for Ubuntu Edgy 6.10, there have been speed improvements in terms of booting, but it still needs some work, and I am sure that it will be optimized by the release date. It has recognized my USB Camera and my USB Flashdrive out of the box, without any work. I had never tested it but its amazing – as hardware support is increasing for Linux and Im extremely happy about that. NetworkManager has recognized my Wired Network connection, which makes me all the more excited. Firefox 2.0 Beta (Bon Echo) is in the Repositories right now, and it is functioning quite well. Epiphany is also functioning quite well but I have experienced some crashes – which I had never experienced before. As for OpenOffice.org, it has the latest 2.0.3 Version. It is indeed faster, and I have been able to open documents faster in OOo than in AbiWord that comes with Ubuntu, which makes me very happy. So, without further ado, here are the screenshots:
