I'm using a beta Lucid also and very happy with it's performance, appearance
and stability. It works on my MSI Wind while the final version of it's
predecessor had an incurable flashing video problem. However, when the final
release version comes out next month I will do a clean install as there may
be fixes and features that I'll need. Then I will leave it alone until the
next long term support release.

Only you can decide how often to upgrade. For the tinkerer there is a new
opportunity every April and October... for us less adventurous types it's
best to stick with the 'long term' releases.
