You must be insane. This is what it is really like.
Office is better than iWork 09.
Pages < Word
Keynote > Powerpoint
Numbers < Excel
How anyone can claim otherwise is beyond me. The only reason to get iWork is for Keynote.
Excel is definitely more functional than Numbers, most people just don't need that much functionality. Word is more functional than Pages, but again, most people don't need that much functionality. I prefer iWork because I prefer its User Interface. However, for either collaboration or electronic document submission, Microsoft Office is better, or at least OpenOffice. iWork can export documents to the corresponding Microsoft Office format, but it tends to lose formatting, and Keynote has effects and transitions that Powerpoint doesn't support. For purely text-based documents, I use TextEdit because it can work with Word documents natively. For documents with text and images, I use Write 2. For Keynote, if you're just presenting, a Quicktime file will be alright, but it loses a bit of quality, so it's better to plug your Mac or iOS device into either a T.V. or projector if you can.
The other reason I like TextEdit is it's a light application which can handle Word and RTF documents natively, without changing formats. With iWork, you have to go through this process: Office ->iWork->iWork. That's why it's good to either have Microsoft Office or OpenOffice. By the way, RTF is a useful format for purely text-based documents because it works on any platform, even if you don't have Microsoft Word or even a program that can work with Word documents. RTF can't handle images, but it's great just for text-based documents. Lastly, TextEdit may seem very basic and bare-bones, but that’s exactly what I like about it. It’s a lot less distracting than say, Microsoft Word or Apple’s Pages. This simplicity makes it a lot easier for me to focus on what I’m writing instead of how it looks, or being distracted by the program’s User Interface. Also, unlike Google Docs, I don’t have to worry about server failures. I use TextEdit whenever I can because it’s preferable specifically because it’s less distracting and I can save my work as RTF documents which work on all operating systems as well as Microsoft Word documents.
