I am not openly hostile against Ext3. But I think it's dangerous for someone to convert their player's filesystem if they don't know what they're doing. The person I responded to didn't sound like they were the appropriate customer for the Ext3 product, hence my recommendation to go back to the original filesystem.

I think that encouraging everyone to convert their filesystems before the stock software supports it is a dangerous thing to do. I think stiffer warnings should accompany your recommendations for it.
