Since the forum is locked to new members, the OP is preaching to the choir if endorsing CbB. For a
new DAW user, onboarding costs are definitely a consideration, and the "rent to own" is essentially zero-percent financing (it is actually 0.0806% APR over 24 months - $0.33/month extra or $7.81 total) which is far better than SONAR's was to get Platinum. For those who owned X2 or better (before CbB was released, which probably doesn't qualify), there was always a standing crossgrade to SO Pro for $100 off that became $200 off during the holiday season (which is where it sits now). To my knowledge, SONAR never offered such.
Also bear in mind that CbB does not come with a great deal of 3rd party goodies anymore, so owning SONAR previously tilts the scales a bit... a new DAW user isn't going to get them and "free" will mean a lot less to them as well.
*IF* (and that is a
HUGE if) CbB does qualify for crossgrade, which I highly doubt, then CbB would be enticing to a new DAW user just to save $200 on SO Professional. For those that owned X2 Producer, X3 Producer, or SONAR Platinum, SO Professional is $199.95 now as a new SO user (can rent to own that from Sweetwater for $216).
