I'm actually waiting for the next imac update. Hopefully apple will start using penryn in the imac's I do know however, that this wont come about until the the mac book pro is updated. Which also should be using the penryn chip. Well I was just checking dell and hp. It seems, that they don't have many penryn based laptops out. Hp has 2 models while dell is about to release their first model. Is their some problems with these penryn chips. Why are they not more abundant. The updates were waiting for might be further down the road, then most are hoping for. Especially for the imac.
