Above is a good piece of equipment that will do what you want - and record the sound in a format that you can actually use elsewhere.

In that regard I would avoid the Olympus and Panasonic offerings. They will record your sound in some proprietary format that only their desktop applicataion can hear - bad move. You are basically DRM'ing your own recording against yourself. Avoid those things. They defeat the point of digital recording.

Also any Windows mobile smartphone or PDA phone is capable of running software that can record your sound as well, to MP3, Ogg vorbis or WAV format. These will be even more discreet, as they look no different than any other phone sitting on the table - but they is recording what you hear

It depends which Olympus. At work, we have lots of the WS-100 Olympus recorders. Those use straight Windows Media format files, and the recorder simply plugs into a USB port. They've worked very well for our purposes. They also appear on the list of approved recorders for Dragon Naturally Speaking. I haven't tried much of that yet; I do know they pick up sound really well.

Just make sure you do that research on what formats the device actually records your music in and whether you can acces them directly in drag and drop. Other wise you will find yourself with a nifty piece of hardware that is fatally crippled.
