sure, it can open them, but then it corrupts them when you save back and try to open with MSFT's office. Even a simple pptx will change the bullets to some funky character, mess up the formatting. It's not hyperbole, its actual real-world corporate experience. I tried recently to edit a pptx for a conference I am speaking at and as usual my linux/LO installation was unable to do so. I really wish it did work, but I just can't honestly say it ever does. try it for yourself, create a pptx in Office, add a couple slides, simple layout, nothing fancy, then save it, try opening it in LO and see what you have...
