Before using Cakewalk products I was using Voyetra Sequence Plus Gold synced to a Tascam 80-8 1/2" tape machine.
I purchased Pro Audio 4 but my computer was not up to the task. After moving to Alesis ADAT Blackfaces (3 of them) I was less enthused about ITB even though I kept upgrading through the first version of SONAR, I skipped version 2 but kept upgrading from 3 on. At SONAR 6 I started to get serious about ITB recording by having an adequate computer and interface and have stuck with it ever since.
I was a Lifetime Platinum member and I'm not one to complain or be bitter about the change of events that led to CbB. It is what it is.
TBH I'm more of a Studio One Pro V4.5 user now but still use CbB to exchange a "tracking" project along with .wav files with my collaborators where I'm the song initiator (eve though I tracked in Studio One) and with collaborators who send me projects in CbB.
I also use Reaper for one collaborator (he's a Mac user).
I have Harrison Mixbus 32-C that I use a mixing desk, not a DAW.
