MOTU's web page makes Digital Performer 7 look spectacular, but MOTU Nation's forum has a slough of disgruntled DP7 users, so I will most likely just hang with 9.02 for a while. The MOTU Nation's forum kept talking about crashes. No thank you, I'll take stability over bells and whistles any day. I was at Logic 5.51 on a PC up until fall of 2008, and consequently missed all the fun with Logic 6 and 7. Logic 8 was a reprieve from the agonizing learning curve with 5.51. It's not like I didn't seeing the Fall of the House of G5 coming. And I don't mind Life in the Past Lane for a while.MOTU will also abandon PPC.
But if Digital Performer which is (temporarily) PPC compatible appeals to you more than Logic8 and the prospect of a future Logic9/10/11 etc. on IntelMac, then go for it.
