Besides being able to play MP3 and WMA files, the Sandisk Sansa m240 also has a built in FM receiver. If you get tired of listening to your own files, press the Menu button and choose the digital FM tuner.
You can preset up to 20 stations by going into the FM settings through the Menu. The FM radio is not too strong as it had a hard time tuning into a strong local station when I was in my house. A low hiss could be heard over each station I tuned to.

The Sansa also records speech and comes equipped with a stopwatch.

I noticed there was no easy way to see how much space was left on the device. The only way to figure this out was to go into the Menu and view the device information.

Since I have been going to the gym recently, I wanted something small I could fit in my pocket. I was looking at Apple iPod Nanos but they are far more expensive and far easier to bend and crack. I did not want a player that I would feel guilty about breaking or caring for. When I was looking at the Sandisk Sansa, I noticed it was the perfect size and the package even came with an elastic armband and case! So if I wanted to run on the treadmill or out on the road, I could strap this to my arm, hit the hold switch and forget about it.
The blue backlight was also a nice touch. It was easy to see indoors and outdoors. The brightness and contrast can be adjusted in the settings menu to suit your battery needs. I really like the buttons as they are spread out on a wider portion of the player. I have large fingers so small buttons would be hard to access while jogging or working out for me.
I decided to use my own USB cable since the included one was way too short. Aside from that gripe and having a weak FM radio, this was a great buy for a 1GB MP3 player at less than $100. The MP3 files were crisp with tight bass. The included earbuds are not that bad and fit quite well in my ear.
