Do you currently use Excel? I've used it for many years. I used to use it on a daily basis along with the other Microsoft Office programs. I don't know if I could live without it. I use it to keep track of lots of things - savings, shopping lists, tax information, addresses...the list goes on. You can get a free 60 day trial of Excel 2007 and other office programs. If you are considering purchasing it, this is a good way of trying it before you buy it.
