Portable USB Software
A great list of portable USB (thumbdrive) software.
I chose to put this post under the small business category instead of technology because of the nature of the link.
Most business people and consultants are always on the run. Instead of having a CD case with you, it may be easier to just carry around 1 or 2 1-Gigabyte thumb drives with all of the listed software on it.
I'm definitely hanging on to this link.
