Not to be a party pooper or anything, but despite all the happiness surrounding X2 (myself included), I'm finding a little bit of "buyer's remorse" and that the excitement of wanting was greater than the excitement of having. I think the additional features in X2 are terrific, I'm especially enjoying the R-MIX module, that's just fun to play with (and unfortunately discovered I did not need to recently buy that vocal eliminator/isolator, R-MIX does a great job with that.) But honestly this feels more like a .5 release (or even a .75 release) than an actual FULL upgrade.
But I guess it sounds better calling it X2 than X1.5
The bottom line is, yes I think it was worth the upgrade price, but I think they missed out on several opportunities to truly make it a full version upgrade. (The color scheme for one thing)
