I just purchased a new Clip Sport (and Clip Jam–more to follow regarding the suitability of each as a Clip+ successor). That Sport is version=1.22 (not the latest firmware for the Sport: see http://forums.sandisk.com/t5/SanDisk-Clip-Sport/SanDisk-Clip-Sport-Firmware-1-27-released/td-p/340602 ) but it supports the un/lock UI described by DFELD2005.
I can also confirm the complaint made @ http://www.engadget.com/products/sandisk/clip/sport/reviews/12yc/ that the Sport’s buttons are very sensitive–simply brushing against them is enough to, e.g., play the previous/next file (and lose one’s place in the file one was playing). Hence, Sport users will probably want to enable and use the un/lock, despite the additional inconvenience.
