Pages to Word 2010 Experience is quite good!
Yea, but they all suck.

My experience shows me seamless back and forth from Pages to Word 2010 on my PC via Box.net. I'm not a the heaviest Word processor, but I frequently develop Court documents and letters without one single problem in compatibility.
My experience with Pages doesn't suck at all. I expected far less compatibility and more problems and instead, I've found none.
A few of the partners at our firm (and we have picky ones) use their iPad for word processing the same way. We don't do much work with Numbers or Keynote, but haven't had as much need for those types of document development on the iPad.
I too believe that MS should make as great a product as they can. Unfortunately, it's all about making money and doing the basic functionality with a subscription will problem bring them in quite a bit of cash. If it doesn't, they'll have rethink their strategy. I hope they have time to do all that.
