Phil Collins singing "Take Me Home" and Mark Knopfler performing "Brothers in Arms" and "Money for Nothing" are fantastic; heck, Elton, McCartney, Sting, Eric Clapton, Sting, Jimmy Buffett, Carl Perkins and Arrow are all great. This is a wonderful concert; I just wish I could have heard it in person.This DVD looks fantastic and sounds terrific--especially on a DTS capable system like mind. I buy music DVD's only if I can see that they have DTS encoding on the disk (Amazon please take note). However, in a few places--just a couple--the sound quality of "Music for Monserrat" falls down a wee bit compared to other music DVD's I have; otherwise, I would have rated it 5 stars.That said, this is a great DVD for those like me who love these artists.

I have just spent 5 minutes trying to get this damn printer to print an envelope without mangling it. Wonderful.

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.
