I dunno that the people over at Cairo Shell are any more guilty of release delays than Microsoft, Stardock and other software companies... developers who want to get their product as close to right as possible before releasing it to the general public.
Sure it's frustrating to have to wait, particularly when you're just itching to try it out, but what would you rather have... a half baked app that consistently presents with issues, or a well tested complete app that works well right out of the box?
As I recall, Stardock has yet to release a x64 Vista compliant Object dock... and that's been on the table for a while. And MS delayed the release of Vista by several months because they felt it wasn't ready. I'm sure there are other cases as well, but irrespective of projected/estimated release dates/times, it ain't done 'til it's done... amd better to be well done than half baked, eh!!
