Re-reading your post, as you suggested, I think people may have taken offense to the statement:
"additional features of version 1 and 2 no major difference to prior version = not cost effective and redundant."
From my perspective, it does seem rather harsh and could discourage people from upgrading by stating that the features are redundant... that hurts WebAssist and in turn hurts our ability to add the features you are suggesting now.
You are quick to rebut when someone simply "assumes you assumed" something, surely you could understand others who don't agree with your assessment can chime in with their own 2 cents when they are pleased with this round of updates and the cost.
I continue to think the price is almost ludicrously inexpensive both for the full version and upgraded. It probably still isn't difficult selling an individual implementation for thousands more than the original cost. The additional feature of options with inventory control is very difficult to pull off effectively, so that feature is very big for those that need it.
We appreciate your suggestions for how we can improve. I think this forum is filled with people that like WebAssist, our extensions, our products, and our commitment to their success. Suggestions with a positive tone would be more welcomed and possibly incorporated into the next version. A comment after the fact that something isn't worth purchasing seems less constructive even when you give potentially valid reasons why.
