don't skimp if you plan on archiving....
I conquer with the statements made in the article about the differences in quality between CDs. I have had misfortunes in using various CD-Rs to record data only to become completely useless after having the slightess scratches (which will occur over time).
At work, we use good CDs internally within our IT dept. and we use 'cheapies' when we distribute data to users on occasion, essentially 'disposable' media.
At home as well I use good quality CDs, my wife takes pics of our young daughter and let me tell ya those pics mean alot to her! It's a small investment for those precious memories!
There is a need for Blue-Ray and HD DVD for alot of ppl and certain types of application (especially archiving 'cause there ain't no such thing as too much storage) but there is too much hype on its necessity for adoptation. I myself am sick and tired of the 'format wars' which is only lending fuel to further fragmentation in compatibility with higher costs and user frustration/confusion which in the end hurts everyone. Afterall, 'media' is meant to be shared right?
