[Q]: not bad but be warned you need to buy extra play-doh at local store before handing it to the kid's
[A]: Positive

[Q]: i find it incredible that so many people speak so glowingly of this book. on the basis of its literary merit it deserves a prominent spot in supermarket checkout lanes. that this is in any way respected as a novel or thought of as remotely historical (pre-historical, is suppose) speaks sad volumes about our society.i guess my one star may be a bit harsh. it's concievable that one could glean some amusement or light entertainment from this. but i feel a civic duty to in bring down the five star average it's garnered so far.
[A]: Negative

[Q]: Where to start I have had this for 10 years and it is still ticking that alone is a tesament to how well the thing works. Over that ten years It has traveled with me to over a third of the world. This is to include half a tour in Iraq. It has been dropped and has been trough airport security more times than most people. Because of this I have never had a reason to buy an Ipod. And to be honest for music I would rather use this. Only reason that I own anything like an Ipod is that its my Iphone. So I think that the Xtra is by far the one of the best mp3 player made.
[A]:
Positive
