I'm working from home today, writing a strategy document. My document pulls from several sources, and at one point I realized I needed to copy/paste some data from a spreadsheet I'd created earlier. So from Word, I tried to open the Excel document.
That doesn't work. Word, not recognizing that this is an Excel spreadsheet that should be opened in Excel, tries to import the file as a document. In short, it's doing the wrong thing.
Under Linux and OpenOffice, everything is integrated. I guess I've taken that kind of behavior for granted. As a Linux user at work, when I was writing a similar document, I sometimes needed to open an Excel spreadsheet when I was in OpenOffice Writer. This worked as expected - OpenOffice realized the Excel file was a spreadsheet, and opened it in OpenOffice Spreadsheet.
I'm continually amazed that Windows and other Microsoft products just don't have the same level of integration and "ease of use" that have been there for years in Linux. Microsoft needs to wake up.
