If you look at the reader survey that Macintouch did last year (about 3,000 laptops) it found that the 15" MBP was the one most likely to have issues (twice as much compared to the MBs) - the main cuplrit was its new motherboard... Apple fixed it.
When any new tech product is launched - be it phone or computer - teething problems are inevitable. A major factor here is that the manufacturer can only do so much in QC and testing (as Sopranino pointed out) and then if the manufacturer is smart, it will take steps to rectify it.
To bowlman23, I think you would be fine buying now, but if you want to play it safe, wait till the next MBP update as (hopefully) most of the current teething problems will be sorted out.
I would, however, have a look at Macintouch - the site has daily reader reports of user experiences and issues. One reason I recommend it, is that there is some editorial control, which I believe puts the feedback into more context than forum reports, as it accurately reports when changes have been made to products and highlights if people are saying things which are incorrect.
I understand what you mean when you say "there seems to be a decent amount of people with problems", but in response have a look at the thread about 'a MB/magsafe nearly burned my house.'
Reading it, it sounds a significant current issue and one poster asked has Apple sorted it out as this was putting him buying a MB. Although I'm not going to say that this wasn't a serious problem to the OP, but Apple begain replacing/exchanging the older magsafe power adapters six months ago - so the issue was concerning MB/MBP's sold last year, but you wouldn't have understood that from most of the comments in that thread, which I think began a few days ago.
Also, Macintouch's reader survey found six (I think) laptops out of 3,000 had problems with the magsafe - now I'm not saying that this was the exact same ratio worldwide for sure, but from many fourm threads about the subject you would have been forgiven for thinking that the issue was a deliberate plot buy Apple to burn their customers to death while they slept.
Forums can be great for getting info, but they can be great for confusing the issue too.
