I have made no secret of the fact that I am a Pocket Tunes Deluxe user, and really enjoy the software for listening to mp3 files. I'm currently using a thumb board skin (available at PalmFocus) which is perfect for thumb operation on a Treo. And, there seems to be quite active development on the product itself, such as the recent additions of Janus and Rhapsody compatibility, plus streaming audio from internet radio via wireless connections. More improvements are on the way.
As a MobileRead exclusive, I can tell you that the Pocket Tunes folks have confirmed to me that bookmark features will specifically be improved, and be a focus area for future releases. I think one can safely conclude that means they are going to address the one remaining significant weakness that I see in the software. Specifically, if I am listening to a set of files in order, say an audiobook with multiple files, it's not very easy to leave that audiobook to listen to something else and then return where you left off.
Technically, you can sort of do that with a bookmark, but when you return to the bookmarked location, you only continue to the end of that file. To continue to the next file, you have to open the corresponding playlist and find the right file to restart. Not too bad, but a bit of a nusiance. Ideally, you could return to your place in the book, and then keep on going even if it moves you to the next file.
So with the expectation of this sort of improvement, it's clear that if you are an audiobook fan or like to listen to music in album playlists, you can have some comfort level with jumping on the Pocket Tunes bandwagon. They haven't finalized all the details and are understandably reluctant to share the details so early (competitors are lurking everywhere!) But it's still exciting to know that these basic needs will be addressed. I can wholeheartedly recommend this great program for all your audio player needs.
