Believe me I would rather use Excel (or other spreadsheet solutions) on the Mac side, but I have a couple proprietary add-ins that only work in Windows, so I'm stuck with it. When working with reasonably large spreadsheets (4k rows, 50 columns, several of those columns populated with vlookups), scrolling, copying, etc are significantly slower when running in coherence mode. Going back to windowed mode gets me back up to speed. Looks like coherence takes a serious memory byte....
