Generally it's advised to have more than one spreadsheet in a
workbook. The
reason for this is that viruses can infect workbooks, and the damage
done by
the virus is often less severe if it spreads over numerous worksheets
rather
than "focusing" (if you will) on one. You will generally lose less
data if,
god forbid, a virus finds its way into the workbook. This is why
Microsoft
ships Excel with a 3 worksheet workbook. Legally, they are trying to
protect
themselves from lawsuits for lost data.

BTW, EULA rules!
