It seems to me that paying $50 - $100 annually for, say, 10 years ($500 - $1,000) is less expensive than updating Platinum for 10 years ($199).
But you don't have the most powerful statement towards a vendor - your annual payment saying you are happy with how things are.
If it happends to 10 000 users not renewing - vendor start asking themselves, what did we do wrong?
There is potential risk a vendor never do that - if all is lifetime updates anyway.
ImageLine was about 6 years after Sonar with 64-bit version - was this due to their lifetime policy?
I'm not saying that is Cakewalk policy - probably people I trust more than many others with my money.
But unless there is something of need for my own use - I do not open wallet - and that is a statement lost, if signing up for life.
I hope Mac version turns out really well in all venues of audio industry. Probably very smart move.
