I may be hard pressed to remember the last day I didn't open Word...and that is why technology is so great. You need Excel functions (nice formula) that many will never use and many people need Word every day. Making them both usable on an iPad is a win for everyone.
I get you. But the question I'm having is... Is Word really indispensable in general? I think many people don't leverage the things that are unique to word. But I guess the same is true of Excel... I know CPAs who have no idea how to do a pivot table (which from my vantage point makes you slightly higher than a novice in Excel)...
But I think that even the more basic functions within Excel are unmatched, whereas a lot more users (perhaps not those in your line of work) could get by with Pages or even email instead of Word. There really isn't an integrated equivalent of Excel (a UBIQUITOUS one) for internet-based document sharing, relative to the way email has largely replaced word processing for the vast majority of users.
