It's funny, Excel was the reason I switched to OpenOffice.
1) Closing one Excel windows closes ALL of them. Often I (or other people I was supporting) would be working on an important Excel file, and then open another one temporarily, close the 2nd one, and then unthinkingly say "no" to the "Do You Want to Save" dialog that you THINK is for the 2nd file, but is actually talking about the very important original file. Oh, and Word (which also has a separate window per document) doesn't act this way at all. Oh, "save more often" you might say? Well....
2) Excel doesn't let you Undo past the last save. This is annoying for a lot of reasons, but is completely terrible when you opened a file with the intent of saving your changes as a copy. Oops, you "saved" instead of "saved as"? Your original document is gone, and pretty much unrecoverable.
OpenOffice just works.
(I don't know if the latest versions of Office addressed either of these issues... and I don't really care)
No it doesn't. At least not for the past two versions of Excel (I can't remember Excel 2003). But there is a button to close the current window or specific window.
Excel doesn't let you Undo past the last save.
Yes it does. At least it has for the past two versions.

Honestly, did you really ever? Those were the only two reasons you switched to OpenOffice?
I never worked at a place willing to put up with supporting the 2007+ versions of Office.
Those were certainly the "I can't take this anymore" reasons, yes. OpenOffice also read the new XML-based file formats better than the older Offices with the converters.
Since then I've also switched to Linux, which simplifies my decision.
