"The market for standalone music players seems to be in three segments at the moment. There are multi-GB players on which you can store your entire music collection, small memory players designed for a few favourite tracks of the moment, and, sitting in between there are players of 512MB and 1GB which allow you to carry enough music for a weekend or even a week away. This middle category is awash with products, and to be a success players need to meet a lot of criteria ... The Sansa comes in two versions. I tried the 1GB version, coloured iPod-ish white and silver. The 512MB version has a slightly different name – it is the Sansa e130 – but shares all the characteristics of this one except for its colour and less generous storage memory. SanDisk has been pretty shrewd to include an SD card slot in the Sansa."The player supports MP3 and WMA file types as well as Audible files for the spoken word. There’s also an FM radio with 20 presets and a stopwatch. While it appears to be really annoying in that you can’t search for tracks or set up playlists, it is operated by a simple AAA and lasts quite a while one the tiny battery. So I guess that is the advantage. Other than that, I would say that this is just another MP3 player.
