Are the Intel iMacs as good as Apple Claim?

A few weeks ago when the new Apple iMacs were released, there was a flurry of activity in the blog space about whether the new iMacs are the perfect machine for Java or not. Since then, I’ve see articles that compare the Intel iMacs to their PowerPC brothers but not any articles comparing them from a developer point of view.

So, does anyone have one of these new machines? Do they run Java better than the PowerPC counterparts?
