I have been using 2007 for a few months now and have had no problems reading
or writing to earlier file formats. The biggest change is the user
interface and that has taken too much time to get used to. Thank god most of
the shortcut keys are unaffected

The other big change is in the huge increase in number of rows and columns,
but to take advantage of that you must use the new xlsx and/or xlsm file
formats. Thus, those files can't be fully shared with people who are not
using 2007

Thank in advance for any suggestions
