Surprising news today coming from a developer webinar hosted by AT&T and Palm. According to one of the slides, Palm will be running a 50% off promotion on all App Catalog apps. Of course this benefits end users, but it also benefits developers who will still see payments based upon the full retail price of their apps. Palm will be subsidizing the promo. For those counting at home, that’s $1 million for the Hot Apps promo ending June 30th, another $1 million for the PDK Hot Apps promo and now this limited time 50% promotion. Palm is certainly doing everything they can to stir up excitement among both developers and end users. The rumored dates for this promotion are June 21st through July 9th.
