#MacOSX

Based on??

Usability and compatibility is a problem. Especially with Numbers.

It is not able to open password protected excel files or excel files with web data queries. Compatibility with Google docs spreadsheet is not in place. Google docs can't import Numbers. You can save Numbers on excel format but Google docs was not able import without errors.

Formula creation on numbers was really hard compared to excel.

An this is just based on 1 day usage. I'm not sure do I want to continue practicing and evaluating.

Pages I like more but is it better than Word for mac?

Keynote I haven't used. There seems to be nice templates.

Everybody is collaborating with office apps, almost always. If you have to save two formats, iWorks and MS complient, what's the point. Doubling HD consumption, space for error (which one was the latest etc).

I didn't like the feel of iWork. Now I have Microsoft Office 2008 and I'm loving it. And it's really suprising to hear myself saying that. :D But yes, Excel 2008 is everything you need.. except when you want to fit data in you graph with equation that Excel doesn't know.

I got tired with OOO and NeoOffice crashing and behaving badly, so that why I changed to MS.

I didn't use Numbers. But Pages and Keynote are great. Use them often and love how and what I get.
