Q: As a musician and musicology student, I am very familar with both the "classical" world of music, and the popular world of music, and I have to say that perhaps string quartet versions of R.E.M. might be interesting, but you need a creative and enterprising quartet (such as Kronos Quartet, etc.) to do this. This CD is greatly disappointing because the transcriptions are simplistic and lacking imagination. String quartet recordings can be very exciting, but not here!

A: Negative

Q: I have been buying Hi-Tec for years. When I found the Altitude IV I fell in love instantly. This shoe fits great, has little break in time and still holds its sturdiness as it ages. Well recomended.

A: Positive

Q: I used this camera for a year untill during a period of a couple weeks of not being turned on, something to do with the light sensor malfunctioned. I think all Canon ZR series cameras are inclined to having buggy hardware and I dont remcomend buying one.
