Is the X7 that bad?

[musichound]

I am zeroing in on a Cowon player, between the J3 and the X7. I am aware they are completely two different players, and the X7 (160GB) is hard disk based where the J3 (8GB-32GB) is flash based and includes a micro SD slot. After reading through the X7 forum, I have come to the conclusion that there seems to be more dissatisfaction toward the X7 than mostly all other DAPs, most specifically because they can become unusable after a certain point in time. I also understand the UI is not that great, but would take some getting used to. I can live with that, but if the failure rate is higher than most other players I am not too keen about that statistic. The J3 on the other hand seems to atract much more favorable coments in general. I also know that people tend to post more when they are not satisfied than when there are no issues, so I am asking this question to all X7 users;
