RE: More than just spreadsheets, it’s also imbeded marcos to call internal databases inside the firewall and external databases via the net.
Why can’t Apple or Google create spreadsheet peoducts that compete with Excel?
Sure they can, but then you're going to have to port all of those old Excel macros over....don't see that as a real good cost/benefit trade-off.
Apple or Google can and probably have.
The resistance is the enterprise risk in converting to them.
To implement for example, the enterprise would have to test all it's monthly reporting on the new spreadsheet; report the faults and get tech support to fix the problems.
Why make the effort? Change is risk.
