I purchased mine at Walmart and after learning all it's features I have to say I'm extremely impressed.
1) This can connect to your PC via a mini male RCA pin on each end of the wire. The same wire you would use for an MP3 player.
2) Connect from recorder's earplug to your PC'S input on laptops (sound-card on Desktops) and Record "What You Hear". Of course you can control the bit-rate of the recording if you choose to.
3) You can also play it through your car stereo if it has an auxiliary input, many cars today do. Use the same wire you would use for an MP3 player.
4) You can make a recording and set an alarm to it to go off daily, weekly, etc. I made one screaming at myself to get out of bed and get to work. Even if it's off and the hold key is set to hold, the alarm still goes off daily.
5) I recorded a live 50's band just having the unit on our table and was really surprised how clear the recording was when I played it back in my car, the drums cymbal's were surprisingly accurate.
6) I enjoy the different folders and once you use them they're great to have.
7) You can also connect an auxiliary stereo microphone and record stereo and it will play back in stereo using an auxiliary source that's plays stereo. Make sure you have an RCA mini stereo plug.
8) When recording do not place it near anything that generates radio frequencies such as a PC or cell phone when transmitting, you will hear background noise if you do.
9) Batteries appear to last forever and in closing, I find this mini recorder absolutely amazing and considering all the features it has and its capabilities it truly is an amazing little recorder for its price.
