Often times the cost of some training courses is restrictive while a training manual might not be. Example: you could attend a weekend to week long course for maybe $2,500 for a microsoft certification. An alternate choice is to purchase a 1,000+ page certification guide or "training bible" for $75-$100.
It seems these days that too often a company creates a great software product and then instead of offering both an inexpensive $100 self-study book and/or a $1500+ live training event; they go straight for the high priced live event and never develop a lessor priced, "self study" training option.
I don't know what Passware might have in the wings as far as training goes. As with other software products I have and use on a regular basis;, a well indexed, authoritative training manual is something I'd be interested in.
