Pros size, battery life (I use rechargeables), design, sound quality
Cons interface takes a little while to get used to and not intuitive, could use a clip instead of the lanyard
Summary I was looking for a small MP3 player with at least 1GB memory and a built in FM tuner to replace an old, heavy, no-battery-life Archos. At first I almost did an impulse buy of an iPod Shuffle, but after looking around, decided the FM tuner was more important to me. The PNY Vibe turned out to be a brilliant purchase. I really like having something so small. The design is quite clever, although the manual doesn't give a good picture of how to "disassemble" the unit to plug into your computer.
I have not installed the software that came with it.
I found the best price at www.buy.com.
