We have struggled with cables for a long time and finally hit upon something that works well. These Cable Manager's by Cleverline
(a Dutch company) are flexible coils that you can wrap and unwrap easily around all the crap that is coming out of the back of your computer, etc. We used to find them at Brookstone, but they no longer sell them, so now we found them here at Cableorganizer.com
for $8.50 (pack of two).
These are particularly good for big bunches of wire, whereas if you have just a few these Velcro One Wraps look excellent. It's sort of a neat site..... These Cable Wrapz look good as well. MGR
