Review: Nice form factor etc...but bad function. Product appears to charge my Powerbook G4 12" when it is off or asleep, but when working it cycles on and off and emits a faint buzzing sound from the brick. Try another product.

True

Review: I got one of the earliest examples of these new devices. They are simple to install and fairly simple to use. In essence, you put it on your keychain, and anytime you hear a song you like (and perhaps want to buy), you hit the button. Then, you attach it to your computer via the cradle, log on to Sony's eMarker website, and by selecting your city and station (you must remember what station you were listening to when you hit the button), it checks the time stored in the unit against the playlist supplied to the Sony website from each radio station. You can get some info on the song/artist, hear some clips, and if you're so-inclined, you can buy the complete song from Sony via download. This is a 'free service', unless you decide to buy the music. In that sense, the eMarker is a clever tool for Sony to sell direct-to-consumer, avoiding the other means of internet distribution now available, as well as circumventing the retailer.

Review: Purchased this radiator 5 months ago. It fit perfectly and performed well for 5 months. The side tank seam started weeping last week. This week it is leaking a lot. I expected this to last much longer. I will purchase another brand next time or go to a junk yard and get one from there.
