Seems to me, Parallels was aware that many people wouldn't be able to get Vista working, hence the term, "experimental". To me, that means Parallels was just giving those early adopters who take all the arrows the opportunity to play with the latest Windows gadget. It also doesn't hurt when they can say they have a Vista-capable app before VMWare does out in the market. Most people wouldn't play with beta software anyway so the universe of Vista users is awfully small at the moment and mostly populated by computer nerds like me who always want to have the latest toys regardless of how well they work.
If you're complaining about the double-whammy of beta software not working well with beta software, perhaps running Vista isn't for you?
How many people out there running Vista also have in their possession an HD-DVD or Blu-Ray player (rhetorical question, of course), neither of which is ready for prime time. 
Vista RC1 also came out a day before they released this beta, so they had no time to test it. Few had the pre-RC1 (build 5536).
