Mac OS X development

Before i start... i love MacRumors, long time reader, first time poster. I am really liking tiger, i've used Mac OS since os 7, and I have to say, Apple is really polishing Tiger. I question the 200+ new additions to the os, but they really improved a lot. Fast searching, rss, widgets, faster interface, better built in burning, better built in photo capabilities. My question is, what is really left to add to the os? They have parental controls, a dictionary, tons of little things that are just making it a complete package, what can apple really do now to truely innovate? Please post some ideas. Mine would be more user friendly. Before I am flammed I mean, zero configuration; period. Apple has is in a great position to do this; they control all of their hardware, and basically what works with mac. They all ready have this started, but i think it should be more developed. When you plug in iSight in, it should work. When you plug in a printer, it should work. When you hook up a scanner, it should work. I am speaking in terms of no drivers or settings having to be configured.
