I would suggest folk don't upgrade to it. They are releasing with a beta version of an Nvidia driver that they switched to only this week. I've been running the 10.10 beta since it was announced, and this beta driver black-screens here unfortunately. I have to run an older driver via a manual install from Nvidia for things to work; the Ubuntu team do not provide an option for this. Even if this problem doesn't affect you, a lot of folk are having 100% cpu issues for some display operations. I can hit this by simply scrolling in a terminal window. Some machines will also fail to suspend. A hack has been made to grub to help with this, but it might also be necessary to add custom parameters to the grub kernel lines. I'm having to use "acpi_sleep=nonvs" so that suspend works. In addition, there is a bug that can cause pulseaudio to hit 100% (on one processor, these days) when unpluggging some USB audio devices. Yup, got that one too. This is the worst release I've experienced on Ubuntu. I've used it since 5.10. This same machine worked flawlessly on 10.04. I get the impression that they were going to release on 10/10/10 regardless of issues. It would take balls not to release it at this point, but that would be the appropriate thing to do. I don't believe it's ready. We'll see.
