I am looking for a digital sound recorder that I can use to record high quality voice audio anywhere I go. I don't need the perfect playback solution on the device itself (because I want to primarily re-listen to the audio on my Mac) but I do want at least 10 hours of good quality sound recording built-in to the device for storage capacity. This is in case I am away from my computer for too long. I will use it both for college classes and for revolutionary ideas that I have. Because of this the ideal device would be one that can pick up both close and far away voices. Please don't limit your recommendations to any one of my preferences such as price, storage capacity and playback solutions. Since I don't have too much knowledge on digital sound recorders I am still looking for advice and am prone to easily change my mind on any one of the parameters that I mentioned. So please feel free to list your views on the best sound recorders. In advance thank you for your advice.
