Others, including cloud based

• Microsoft Office Web Apps:These are versatile apps since they can be used on or off the cloud. Expect a simplified experience to the full version of Microsoft Office suite.
• OnLive: Access both a degree of Windows desktop functionality and full Windows versions of Microsoft Office Suite.
• CloudOn: This was one of the first solutions for iOS productivity. Syncing with Dropbox, CloudOn offers a more complete Windows desktop. The tradeoff is it also offers a more pared-down version of Word, Excel, and PowerPoint.
• rollApp: Offers Open Office programs for iOS, also utilizing Dropbox.
• LogMeIn: Remotely access your home computer's desktop from your iOS device. This solution requires coordination of logins, settings, and hookups. The free version does not offer file transfer, but you can get a separate, free app for that.
• Google Docs: Now featuring Google Drive for iOS, users no longer have to battle with pressing the Refresh periodically to initiate syncing. This makes collaboration much smoother, resulting in a stronger office productivity product.

there's also the built in notes app, but only comes in yellow😀

Ok, I use iwork and they work fine for my needs. Plus, they all synce with my other devices and macs.

I would not expect a ios version of microsoft office anytime soon, at least I have not heard of one. I've heard good things about some of the equivalents though.
