S3 has heightened the standard for entry-level MP3 players with an inexpensive player that includes USB, Mac-compatibilty, and expandibility.
Mac users rejoice, finally S3 (Diamond) has given us an inexpensive MP3  player compatible with the Mac. I own a PC at home, but I'm a Mac user in  my office.
While the Windows software rocks, the Mac's Soundjam software  leaves a lot to be desired. At Mac World companies like MusciMatch were  promising plug-ins for their MP3 players to allow 600 users to manage their  portable players, so maybe someone will develop a better interface.  However, I'm happy to have a player that works without any glitches on both  OS 8.6 and 9.04.
My main qualms with the harware is the on/off switch  because it also controls the ability to turn off the buttons when you stash  it in a pocket. In addition, I don't like the ear-buds packed with the  system.  Plus, don't trust the machine's battery monitor.  When the  batteries inch below 40%, grab an extra one in the event that it  prematurely dies -- I had this problem in the subway the other day.  In  addition, I reccomend Duracell Ultras for the 600, and a good pair of Sony  earphones.
I can't wait for the memory upgrades. While other critics  pan S3's choice to stop using standard flash memory formats, I praise S3  because the company chose the new form factor, so they could use IBM's  smartdrive technology, which are basically small hard drives.  The price of  a 300 mb smart drive is the same as 64 mb of standard flash memory.  Hmm,  60 minutes of music, or 5 hours of music?  Unfortunately the smartdrive  backpacks won't be available until Christmas.
This player is ideal for  both Windows and Mac users because of S3's embrace of smartdrive  technology.  However, if you already have a player, but are looking at  nextgen models with USB, wait until Christmas when the smartdrive  technology is available.
