I bought a NexBlack from Frontier Labs at the end of august 2006, when it went out after something like one year of waiting.

It's the perfect audio player for me: plays Ogg and MP3, with removable standard battery (no battery that you can't change yourself), removable memory (here it's Compact Flash and it's in my opinion the best: more than 8GB of max. capacity, not too big, not too small that you can't loose it, cheap), with line-in recording and a battery life superior to 20 hours.

Received it a couple of days after, it's really a good player, except some firmware bugs: can't recognize Ogg Vorbis tags (so you can't find an Ogg file by Artist, album or genre :( ), can't recognize international characters in english setup (i'm french though), and some minor ergonomy things. It's really beautuful to me, and useful. Playing is gapless between tracks (Vorbis or MP3). Sound quality is probably the best i've heard at this day (with good earphones, the ones offered with the NexBlack are just awful).

Sadly my joystick "down" direction broke down some days after receiving the unit. I'm waiting for a replacement unit, Frontier Labs are saying that it's not a flaw on all units, but just a defect on my unit. I hope they're right :) But I will not change for any other player, this one is perfect for me :)
