Samsung YEPP YP-Z5 (2GB, black)

Pros: Great sound, interface, and support.

Cons: No on the fly delete

Summary: I bought this unit back when CNET first reviewed it, and thought it was great then. I just wanted to note here that CNET's review is outdated due to subsequent firmware updates by Samsung. My unit shipped with firmware v1.6 and is now up to v2.45. Every new firmware release includes new features and refinements. My battery life is now up to a whopping 44 hours!! The unit now has UMS only mode as well as MTP, supports album art and sync'ed lyrics, a seven band custom EQ, supports OGG format, gapless playback, a 24 hour clock, and an on-the-go playlist. The touchpad sensitivity has also greatly improved, although navigating zoomed photos is still hit and miss. It also comes in a 1 Gig flavor. I highly recommend this DAP. I use it mainly (for 6 months) while working in a dusty, dirty environment and have yet to kill it. Very durable.
