Based on some of the things I've read on this board, it seems like more than just minor bugs.

Keep in mind that on bulletin boards, you only ever see the people who are having trouble. For each person with a complaint, there are many more who don't have that trouble and are therefore happily enjoying their product rather than posting on bulletin boards.

For instance, the problem with the track order being reported above is something I've never encountered on the Karma. When I queue up Dark Side of the Moon, for example, it plays in order. (And gaplessly, I might add. )
