[Q]: I am a country and western fan in Memphis. This new Sony product is great! I meam really great. I don't have to remember songs I hear on the radio anymore. Definitely worth the $19.99 I paid. Get one!
[A]: Positive

[Q]: A classic story based on history. One of Hypatia's crimes appears to have been ready to provide a hypothesis of a heliocentric universe, long before Copernicus and with a much worse response from the Christian community.
[A]: Positive

[Q]: We got these as a gift for our one year old. He loves them! He tries very hard to get all the little things out of the blocks - and obviously fails. He loves that some of them move, some of them jiggle, some of them make noise - its almost an adventure!The three year old also loves them because they incorporate the alphabet and he can easily identify the items inside: B - Banana, P - Penguin, U - Umbrella, Z - Zebra.Bonus - when the 1 y/o gets frustrated because he can't pry the items out of the block no matter how hard he tries, he usually flings them. The 3 y/o tends to use them to build walls or towers for the sole purpose of smashing another toy into them, or dropping them off high places. And I've stepped on two of them already. They seem to tolerate this treatment rather well.
[A]:
Positive
