I really don't like flaming but some of the posts on this forum are just completely ignorant to the real world.
All professionals use Microsoft Office because it is THE de facto standard in the business world. It is an absolute joke to send a business contact something made in pages->converted to word and hope that it formats correctly (same for excel and especially powerpoint!). I could list the billions of incompatibilities but most are intuitive - all formatting that is done to a document has to be interpreted correctly on the other end. There are thousands of things that can and will be misinterpreted. iWork is GREAT for personal use, TERRIBLE for professional use. It doesn't support all the many things professionals need - professional endnote applications, scripts, reviewing, collaboration over a network, the list goes on......
Bottom line, professionals use office because it is the standard and it performs its job better than anything else at this time. While I love apple, iwork is terribly inadequate at this point both because of its own inherent weaknesses, but more importantly, because it is not supported by many specialty office add-ins that professionals use.
To the OP: I would LOVE office for iPad to finally view powerpoints correctly on an iPad.

I'm really, really glad to see others sharing this view. I would almost say (perhaps at the expense of sounding arrogant), those who do not understand the insufficiencies of Pages probably aren't using it professionally.
