first of all, i found iListen 1.6.x very easy to use. i had to train it first, but once trained i almost always hits the right word. correction done with the mouse and keyboard was easy. this software beats anything else available for Mac or Windoze.

as for the $39.00 price, it's clearly marked on the iListen site as an upgrade price. when VersionTracker lists license = update then the price listed is the update price.

finally, i completely agree with iMarc about 2 spaces after a period being outdated. as a professional typographer, i have explained to countless clients why i will not double space after a period, no matter what they were taught. with proportional spacing, periods and commas are set a little to the left of their spacing block, in order to increase the spacing after the period without having to double space. it was done that way before the monospaced typewriter, and should be done that way now.
