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: A Charlie Brown Christmas is my personal favorite Christmas movie for children of all time. The movie is entertaining and funny, just as the peanuts movies always are. Mostly, though, I love the fact that this movie pulls no punches when dealing with the over commercialization of a sacred holiday. Indeed, the movie comes together with Linus quoting from sacred scripture after Charlie Brown asks in frustration what the true meaning of Christmas really is.If you are parent who wants an entertaining Christmas movie for your kids that doesn't attempt to gloss over the true meaning of Christmas by using gushy messages about peace on earth and family togetherness, but gets right to the point of Christ's birth, consider a Charlie Brown Christmas. You won't be disappointed.

Review: I've enjoyed reading this edition for its critical essays and helpful footnotes, but the copy I ordered from Amazon was missing thirty pages. (It turns out that pages 14 through 44 are printed twice, resuming at page 77). They may have corrected the problem in other copies, but don't assume that you'll get the whole book! 
 Polarity: Negative
