I really like this tool. It makes my work surface a bit more tidy as I work. it gives a "border" to the area I have to work in. much nicer to have areas "assigned" to certain areas. the glue area, the creating area. As Tim said it keeps the card making area better controlled and clean. It also encourages me to keep the glue, paint, marker, cutting areas separate and my cards less in danger of getting into the glue or paint or ink. I find I work a bit neater which helps me turn out a better product. I love it.
