system
You are a helpful assistant. The assistant first thinks about the reasoning process in the mind by using Belief-Desire-Intention (BDI) framework and then provides the user with the answer. The reasoning process and answer are enclosed within <think> </think> and <answer> </answer> tags, respectively. 
Below is an instruction that describes a task. After thinking, when you finally reach a conclusion based on the customer's intention, desire and belief, clearly state the BDI thinking process within <think> </think> and then the answer within <answer> </answer> tags.

User Review: I got my Nomad Jukebox (NJB) just over three weeks ago.  I am a committed MP3 fan, and I have owned both the Rio 300 and Rio 500 players.  The NJB is, far and away, the best player on the market in terms of durability (Rios don't last in my experience), price/capacity ratio, playback options, and recording.  If you have gotten this far, you probably already know all the specs.  Here are the glitches I have found, and some solutions I recommend.
1.  In my opinion, the battery life is the biggest limitation of this product.  This device is a portable harddrive, and it eats power.  As a result, Creative provides two sets of four 1600mAH rechargeable AA batteries.  They look like normal Duracells, but a standard disposable battery contains about 750 mAh.  This is milli-amps, a measure of the storage capacity of the battery.  Four Duracells would probably last about 10 minutes in this thing.  In short, you need super-batteries to run the NJB properly and the company gives you only two sets.  Each set, when fully charged, get **optimal** play life of four hours. Plan on less.  If you travel a lot, like me, and want the NJB for longer trips, you need to buy extra batteries and an external charger. (It comes with a cigarette-lighter adapter for the car)
To optimize you batteries with the NJB, buy extra sets of 1600mAH batteries, and an external charger.  Get a charger with a conditioning feature that fully drains the battery before recharging.  You can run the Jukebox with no batteries inside, just connected to the AC.  I always run my NJB on AC when available, and only charge my batteries in an external charger.
2.  There are some annoying problems with the NJB that the company plans to fix soon.  A few a really important for DJs who might want to use this for dance mixing.  There is no A-B looping feature within a track, and the NJB places a pause between tracks that you cannot eliminate.  These will be fixed, appartently in future firmware upgrades.  My advice to people looking to use the NJB for DJing -- hold off the flurry to buy now, because the features you want are still a few months away.
3.  There is another annoying problem that really irks me.  The NJB can only recognize one song title, even if the album and artist are different.  So if you want to put Ella Fitgerald's and Billie Holiday's version of "All of Me" on your NJB, you have to rename one of the tracks, e.g. "All of Me 1" and "All of Me 2"  This is annoying, especially for classical music and jazz fans.
4.  The cool headphones are not very loud.  Many NJB users I know have purchased headphone amps to increase the sound.  I am not much bothered by this, but you if like LOUD headphones, you need to buy another gagdet to get the most out of this.
5.  Perhaps the biggest design flaw is that the reformatting function for the NJB is triggered by pressing "play" and "stop" together.  Since they are the two largest buttons on the player, this was a mistake.  It hasn't happened to me (you have to respond Y or N to "reformat?" ...I'm not that brave..) but this seems like a stupid mistake.
6.  Plan on several weekends of CD ripping.  I still have 2GBs to fill after intensive copying sessions.
7.  You can not upload files with the .mp3 extension from the NJB back to your computer.  But you can upload files with the .wav extension from NJB to computer, and you can simply add the .wav to any file on the NJB with the enclosed software.
8.  As for the enclosed software, PlayCenter 2, its an adequate CD ripper/Mp3 encoder.  Creative didn't spend a lot of time on the software.  If you have a favorite encoding software, don't chuck it until you check out Playcenter.  Its really weak, especially with multiple file transfers.
9. You need a pre-amped mike to record on the NJB.  Basically this means a mike with a battery in it.  I have one, and have made one recording.  The recording is awesome, and very simple to do.
All in all, the NJB is GREAT.  I love it, I use it everyday.  but there are some glitches that will be fixed in future upgrades, or at least you should be aware of.
