I really love my iPod Shuffle. It´s small, has a good battery life, looks good and has enough space for my music (I don´t need 40Gig, the bus journey aint that long!).
There is one thing about it that is annoying me though. The fact that you can charge it by shoving it into any USB port is great. I have a linux server sitting on my desk with USB ports on the front and this is perfect as an over-the-top iPod charger. The problem is that once you plug it into a USB port, the iPod stops playing through the headphone socket.
True, I could just install iTunes and play though that, but my Linux server doesn´t have a keyboard, mouse or monitor let alone iTunes installed. I´ve got a second set of surround sound speakers in my office purely to plug my shuffle into and all I want is to be able to charge the thing at the same time! I might have to put the electronics degree to work and build something.
