[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

[Q]: This DVD is one of my all time favorite musical DVDs. Miss Jackson proves why she is the highest paid singer in the industry. With a combination of costume changes, great choreography, Janet's greatest hits, and a sold out crowd at Madison Square Garden, the DVD makes for an excellent night of entertainment. I only regret that I was not able to see the concert in person here in my home town due to a cancelation of the concert;however, the DVD is definately a suitable substitute. I highly recommend this DVD to any fans of Janet, lovers of music, and owners of quality DVDs.
[A]: Positive

[Q]: Don't get me wrong, this is a totally enjoyable listen, but is it just me or is every single song on the disc the same. Hell, they're even the same as on Cold & Bouncy, Hawaii and Gideon Gaye. The one thing that makes this album different is John McEntire's wonderful production and the 'Lab girls. If you dont own any High Llamas disc, start here... but if you already do, dont expect anything new.
[A]:
Negative
