I've had mine a couple of months and it's brilliant! Try getting it this cheap in a Sony Centre! They're still well over the hundred pounds mark! It's compact and easy to use, position it right (next to walls, etc) to get the best acoustics, it really packs an impressive punch for its' size, and the fact that it has one speaker is never something that crops up.
The internal battery lasts pretty well, and having a remote control is handy. (Boom! Boom!) I obviously liked the red colour, my friend also bought one from Amazon and I knew straight away that I would get one! The white to me looks tacky (In the plastic, as it were, I've seen one on display - it's like a storm troopers' lunch caddy), the matt black is a bit bland to my liking, this two tone is my personal preference, it's the Darth Maul of the three. I don't know why the Star Wars references sprung to mind, I'm not even a fan of the series! The only slight thing to warn about is that the ipod easily disconnects if you handle it clumsily when moving it about, which is nothing bad about the product. Anyways buy one if you know what's good for you!
