"Gee, back when you were supposedly opening up one member of your bloatware office suite it didn't occur to you to apply that strategy across the whole product line?"
As much as I agree with you on the principle, there's a little technicality that might have played a role here: The so-called "MSOffice suite" is actually a bundle, not a suite. Deep down, the file formats are actually not fully compatible. That's even still true with OfficeOpenXML. There are still a number of -basic- tags that are not compatible across the, erm, "suite". If you want a suite, try OpenOffice (that won't solve the bloat issue, though. Bloody bloated OpenOffice. And you will need Java. Bleuargh. But that makes it kinda cross-platform). Or you could try the Gnome Office "suite" (Abiword, Gnumeric, Evince, Evolution; but then you're stuck with PDF as an cross-platform interchange format for onscreen presentations, and that won't cut the mustard in today's world. Plus, it's not really an integrated suite either).
My favourite mix is currently Evolution , Gnumeric , OOImpress , and OOWriter .
Of course, whenever it's down to paper -or ps/pdf- output, I use good software instead... because let's get real, all WYSIWYG/point'n'click desktop apps are crap anyway.
How do yo like my purple hairdo?
 the Outlook that doesn't suck -matter of taste. Some might like security holes.
 the Excel/OOCalc that doesn't suck -well, not as much as Excel or OOCalc, at least.
 sometimes you just *have* to get a .ppt input/output workflow. Life sucks.
 sometimes you just *have* to get a .doc i/o workflow. Life sucks (bis). And OOwriter has better compat with word2007 than word2003. I kid you not. On one of my machines I am running both word2003 and OOWriter; any word2007 .doc document that features comments or tracked corrections is virtually illegible in word2003, yet displays fine in OOWriter. Docx documents cannot be opened (natively) by word2003, yet you can open them in OOWriter (the comments and modifications might be a bit messed up, but it's still good enough for emergency NIH grant submission!).
