You have to figure that sooner or later the pupil will learn from the master and in this case it is SanDisk, the folks who literally invented the thumbdrive and flash storage for not only Windows devices but also any USB-compatible device, which includes audio products as their SanDisk Sansa Clip+ 4 GB MP3 Player brings fine sound from a very tiny device. As the old gag goes "how tiny is it?" Well, if you were to clip the Clip+ to the inside of your slacks or your shirt pocket, the only way someone would be able to tell you were listening to anything is by the set of earbud headphones in your ears. It is that tiny or, to put it in perspective, it is 2.2 by 1.4 by 0.6 inches and weighs 0.8 ounces. Yet, this tiny device with its built in 4GB of SanDisk memory can hold up to 1,000 tunes or more than enough for anyone to listen to in a trip to just about any place in the world. It is true there are other players that deliver more source material, but, let's be honest, are you or is anyone you know going to be able to listen to 1,000 tunes in anything short of a very long walk? And, not only is the Clip+ capable of a minimum of 1,000 tunes, it can also be used to upload up to 2,400 JPEG video files or 12 hours of video. One of the keys that no major computer firm will like is the operating system of the SanDisk Clip+. The operating system is Open Source, Linux. It's not Android (Google) and it's not iOS (Apple) and it's not Windows 7 (Microsoft). It's just a plain old-fashioned Linux audio player that doubles as a source in itself because it offers up to 40 channel presets so that you can actually set it up to find and update the material you have already uploaded. The Clip+ supports most popular audio formats, including WMA, MP3, FLAC, Audible, secure WMA, and Ogg Vorbis. It will run up to 15 hours on a single battery charge, which is also a nice feature. And, then there's the memory expansion capability of the Clip+ as it recognizes microSD, microSDHC and microRadio cards. This means you can take a whole library of micromusic with you and you never even have to touch anything by your SanDisk. It's a small item with a very large future.
