Hi,about upgrades and prices,well as a total newb @47,I bought Studio[boxed] for $199 from Gigasonic[+$70 shipping],as no one had it in Australia,even in May 2011,then I realised I wanted Producer,and bought another boxed version for $300[+$30]and of course all the Expanded/Pro Channel modules,last September/October.
Quite frankly,compared to my old days of the occaisional[very] mega dollar studios[paid for by the record company luckily],and learning of early Pro Tools for $20,000,having this stuff,even after,buying X1 twice,I still think its amazing value.
I could easily do without X2,as I'm only really coming to grips with X1D,but if it's a $99 upgrade in December,I think that might be pretty cool,although I did like having the security of having the box/discs,and not having them for a whole NEW platform could be a little disconcerting.
Cheers
Bob
