Quantity wise, I would say your point is made and I will stand corrected on that. There haven't been dozens of programs made yet for the reader by 3rd parties. But the programs themselves being made and developed DO make a large difference to those that use them.

There are the several conversion programs being continually worked on for changing already existing content into ereader compatible files. There are a couple of very good PDF conversion and cleanup programs out and still being developed for making already existing documents more usable and easier to read. There is a mountable file system and alternative to the Connect software (which is all Sony has supplied and has had only one update as far as I know since commercial release). I will stand by my statement that these programs have increased usability "massively".

I will also admit that as a single guy perhaps I toss the word "massive" about a bit to much but as long as no one has a camera or a sober memory, there's no proof of mis-advertising.
