About portable applications again

Portable programs can be run from usb drives or cd roms. These programs are made by those experts who use their original software to produce a compact one containing only the essentials. After all, most of the time we don't use those complicated functions. What we want is getting our job done with the same software in its simplicity - the portable version of the said software.
I hope readers who have read my earlier post have gone the the forum site I mention to grab some use portables for their use.
