The Creative ZEN is so close to being perfect, expect for a few quibbles (such as SD card slot usefulness), but it has now become a step closer to perfection. It has recently received a firmware update that fixes and adds a bunch of things like Thai language support, improves startup speed, ensures the alarm is working even if your player is turned off, improves the power adapter charging process and improves video playback performance. The firmware update is titled 1.10.05 is available now and definitely recommended to anyone with a ZEN.
