"I am very excited at the prospect of Ubuntu 9.04 (Jaunty Jackalope) debuting in April, but leery at the same time. When 9.04 is released, I will probably wait until the middle of May before I even think of upgrading the OS -- unless there is some super-awesome improvement that I must have. Heck, the change may even wait until June.
"As an administrator, I know to avoid Microsoft releases until at least Service Pack 1, and sometimes even later. With Ubuntu there had never been an issue until 7.04, but that debacle caused me to rethink my lead time after a release. Since then I have been waiting at least a month for the last bugs to be squashed after a release. I will wait until the first batch of updates after 9.04 formally releases, just to be safe."
