This'll be short. I read a review of the current incarnation of Ubuntu 10.04, code named "Lucid Lynx" at the In a Tux blog this morning. The author pointed out a number of flaws, great and small, with the Lynx but finished up the review by saying, "This version of Ubuntu 10.04 is not a stable or final release of Ubuntu, so some of these thing my change. Please do not judge them to soon" (and the spelling errors are the sole property of the In a Tux author).
Since the Daylight Savings Time change has "jet lagged" me into near-incomprehensibility (and that's hard to spell when you're really tired), I wasn't quite sure when the Lynx was to be released and I decided to look up the release schedule at Ubuntu.
According to wiki.ubuntu.com, we've got a solid 6 weeks until the Final Release becomes available on April 29th. In fact, the Beta 1 release is still four days (March 18th) off as I write this. While some betas can function almost as well as the final product, you should expect a beta and particularly an alpha (and the best the In a Tux author could have been working with is Alpha 3), to have a few, or more than a few, outstanding bugs.
I'm not being critical of reviewing pre-release software and in fact, it's a necessary part of the development process, particularly in the open source world where all contributions are important. Yet, I agree that the Lynx shouldn't be judged too harshly while still in the womb, so to speak. You can find all of the currently known Lucid Lynx bugs at wiki.ubuntu.com, so you'll know what bumps in the road to expect if you decide to sample the Lynx as it exists today.
I'm particularly interested in this particular release of Ubuntu since I've been using the previous Ubuntu LTS 8.04 Hardy Heron and am looking forward to upgrading.

Waiting for something can be difficult and, after all, in the world of technology, six-weeks is almost an eternity. If patience is your virtue though, April 29th is right around the corner.
