By inexperienced, I think we mean that he hasn't yet matured enough to accept the responsibilities that come with the stardom he will go through post-Idol. Being on Star Search doesn't make him any more experienced than any of the other contestants, although it does show that he had an amazing voice from a very young age. I mean, just look at some of the other contestants, most of which are no longer there: Michael Johns, David Cook, Brooke White, Chickezie, Syesha Mercado, Carly Smithson. As opposed to little David, these people are ready to sell albums. If David Archuleta waited a little longer to accustom himself to the stage & his performances, I could definitely see him being a successful singer. Right now, though, his nervousness with his fame already before the show is even ended hasn't done it for me. He sometimes looks terrified of his fans! David Archuleta is obviously great for his age, there's no denying that. But with time, he will get better. David Cook is just flat-out great, age not being a factor. This competition is not about who is most talented for their age, but rather who is most talented.
By the way, vocal paralysis is a serious condition, no doubt, but the fact that he has been through it doesn't make him any more impressive than David Cook having high blood pressure.
I won't be angry if David Archuleta wins Idol, though. I suppose he needs all the help he can get to get his career started, & as long as David Cook gets a record deal (which he will), I'm fine.
