Numbers Comes Through When it Counts

I use Numbers for all of my spreadsheet tasks. I also use it for form creation, signs, some inter-office documents. I like to use Numbers especially because the tools are intuitive, and consistent. Portabaility between Numbers and other spreadsheet programs is seamless. This is expecially useful when working or collaborating with PC users who likely are using Microsoft products. I have never had any significant issues when sharing files with Excel users.
