Task: Sentiment_Analysis

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: My only complaint with the iMP-350 is that there is no way to upgrade the firmware if you use a Mac. I'm not about to spend $$$ for Windows emulation software to run one measly .exe file. Most likely I will have to upload it to a networked Windows machine, run it, and then download the resulting file to my Powerbook to burn to cd. A bit of a pain all in the service of not having to pony up for an ipod.
Otherwise this little piece of hardware has been a delight. It is small enough to fit in the hip pocket of generously-pocketed jeans and tough enough not to skip if you walk determinedly up steep hills while wearing those jeans. A few have complained about volume, and with the factory-equipped phones it is a little weak and has no bass punch. I would suggest investing $$ - $$ in a pair of namebrand earbuds; I've used mine with Sony's and Sennheiser's and it is plenty loud and bottomy with either. I ride mass transit rail and have no problems drowning out the screeching wheels without even turning it all the way up. In fact, being the meek passenger I am, I often find myself turning it down so as not to disturb those around me.
And with good phones it sounds great. The user eq is somewhat rudimentary, and there is no way to boost the mid frequencies, but a little fiddling gets the bass up there where it should be and the treble bright without hurting your ears.
I have had no problems with playback of mp3s. When I bought this I thought I would listen to audio cds more often than mp3 cds, but after burning 12 hours of music each onto 4 disks, I have had no real desire to carry around a library of audio cds. So I can't comment on how well it handles those.
The remote is very nifty and controls almost more functions than you'd want it to. For instance, I have yet to come up with a good use for the feature which allows you to loop excerpts of any length. Perhaps if you enjoy rapping to yourself this would come in handy. The user's manual, though, is cryptic to the extreme.  The best way to learn how to use the remote is to press each button--and they do different things if you press them for a long or short time--and see what happens. The display backlight is a very pleasing shade of blue.
One thing that I really appreciate about the engineering niceties that went into this are "hold" buttons on both the main unit and the remote: engage them and none of the buttons on that part of the player will respond when pushed. Maybe this is a common feature but I realized how handy it was when I found myself inadvertently pressing buttons while the remote was hanging from a front pocket.
I had buyer's remorse for about 15 minutes after buying this player but it passed quickly and now I never leave home without it. Quite possibly one of the most rewarding purchases I've made this year.
