@ Xephyr, I'm stoked for you! You're going to have a great time getting to know it. I agree on the data port "flap" comment. I'm not going to concern myself though. I figure, my others players don't have a flap and they've been fine. So, if it comes off, fine. x2 on the manual comment. Where in hell can I get a complete UI guide?!
A Plus: I'm loving the J3, everyone. Everyday I find something new that wows me. Yesterday, I learned that from the music player's contextual menu (tap the Artist/Title menu bar for a submenu drop-down and then tap the EQ icon) you can change the EQ profile without backing out to the main menu and then into settings. Very very convenient, thoughtful and cool.
A Minus: We're still on our honeymoon, but we had our first spat. Embarrassingly, I haven't gotten the sleep function to work without a hitch yet. Is it me, the settings not making sense, the code? I dunno. Perhaps I need to just try it while listening to music. Anyway, I set it to sleep in 120 minutes and fell asleep to Iron Man. When I got up, the J3 was dead. I couldn't wake it up. I indulged in a quick little freak out session, and then put it down and approached cautiously in a couple minutes.
To get it to power up, I had to hold in the reset button and then press power. I'm an IT pro in "real life" so it only took me a couple minutes to stuff my emotions and remind myself it's just a "system". Still, What? And where's that particularly helpful tip in the guide? Yeah. Nowhere. BTW, no data loss from the "soft" reset procedure.
