Well, you have like a dozen Hell yes votes, one one person with issues still. Count me in with the "Hell yes!" votes as well.

I LOVE the multiple undos, and use the morph tool all the time for popthrough issues, and minor adjustments.

Memory use is better, one guy in th eusenet group has used 20 mill figures in many scenes, and has not been able to get  P7 to crash yet. Material handeling and performance is much improved, and multi threaded rendering support is also built in now as well.

P7 render MUCH faster on my dual core sustem then my sads olf P6 used to, in some cases almost twice as fast. Where I used to always use lower render quality for speed's sake, I usually have my renders cranked to ray tracing now or better.

Then there is also AO and IBL lighting additons, and skin sub surface scattering for that really realistic skin appearance.
 

Way too many people take way too many things way too seriously.
