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: 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.

Review: This is a DVD with footage of a "Come Out and Meet Thomas" day mixed in between the episodes. Sort fo a promotional piece to be honest. Still decent enough to rent. The DVD extras are limited and not very good. My son seems to like it o kay but it gets pushed aside for more interactive stuff to be found on Sodor Celebration. There is also a ton of toys shown during the "party/interview" footage which can be a good or bad thing depending on how much you need to control that sort of thing with your child. Also I for one get annoyed at the interviewes not sure why they just annoy me. This production has the feel of an old VHS video copied to DVD without much added to it. I wouldn't throw it out but I wouldn't buy it either.
