I love the ribbons
What is stupid in Office 2007 is using Excel for charting in Powerpoint instead of good old Chart app?
Why? I have spreadsheets that are huge and take ages to calculate, and I can only have one open at a time (even with multi-core CPUs, tonnes of RAM, Vista x64, etc.); so when I try and draw a chart in PP it create a new Excel sheet and locks my computer, which then works at a snails pace whilst I paste a table of numbers in.
Charting does not need Excel functionality in it's worksheet view, it just needs to accept numbers and plot them.
If web apps are going to pwn the lower end of the spreadsheet market, perhaps Microsoft have no choice but to support the high end "power users"? I would like to think so ... therefore I would like better memory management, more multi-core support (2007 doesn't do all functions), more 'professional' chart options, better stats functions and support, etc.
