Oh, and another thing: Why two CF slots?
Instead it should be cheaper to manufacture a single standard IDE header. Why IDE? it is more flexible, you are not tyed to CF and its adapters. You can inexpensively connect any sort of drives and even buy cheap bidirectional sata converters, even CF adapters if you wish to. With two CF slots, you can only use memory cards, no optical media, no SSDīs, no SCSI adapters, and more importantly, it is not standard enough to become future proof.
