I bet we'll see CF for a long time, because it is the only cheap removable media to support IDE emulation and be bootable from an unmodified PC BIOS. SD is cheaper and will soon provide larger capacities, but it still requires a separate controller and is not bootable with standard BIOSes. Anyway, in my experience, libata supports CF on embedded controllers pretty well. So maybe we should start marking IDE drivers deprecated to encourage people to try libata instead and report breakage if any. The real issue on embedded systems is that the devices names change. On the one hand, it increases portability across models, because you don't have to care anymore about hda/hdc/hdd, your CF is always on sda (major reason why I'm considering a switch BTW). However, for systems which were used to always see system disk on hdX and data on sd* (USB, SATA or SCSI), it might take more time to switch due to automatic numbering.
