In my opinion, the beta is going very well. They have released 3 versions in the last month and a half, the latest being beta 2 Ver .48 just today. I am very happy with the player and MonsoonMultimedia seems to be very responsive to comments.

I think the HAVA hardware is a worthwhile purchase but you'll find other opinions and experiences as with any new product. I intend to use it with both my N800 and my laptop.

BTW, although I have not upgraded to Diablo OS2008 yet, the HAVA Mobile Player current beta versions are compatible with Diablo according to the release notes.
