Have you had the chance to upgrade to Reason 3.0? I know that you said the Combinator was of particular interest to you, as you were still using Reason 2.5 at the time of your interview with Propellerheads.
Yes, I just loaded Reason 3 a couple of weeks ago. The Combinator makes all the difference. I'm just treating it as one powerful synth really, with each instrument as separate oscillators. Combining 3 or 4 Subtractors and a couple of NN-XT's with analogue samples of my Prophet makes for a pretty powerful patch.
Very useful also for textural, ambient loops and morphing FX.
