Why upgrade?
I have supersuite, therefore I already have all 8 extensions included in Design Extender.
Why would I want to pay $39 to get 8 things that I already have? What is the advantage?
I'm assuming that to install Design Extender, I would have to un-install all 8 extensions first. So I spend half an hour or so un-installing them, then I install Design suite, and I'm back where I started. For the privilege of this pointless waste of time I have to pay $39 ?
I can't help thinking that's a bit odd!
