Well, it's like replying to a news about the new Canon 1D-X with "No thanks my iPhone Camera is perfectly fine"
iWork, despite being well-thought for casual users and OK for light home use, is definitely not playing in the same field as Office.
Well - let's be more specific :
- Office is the worldwide corporate standard
- Keynote is almost on par with Powerpoint (even slightly better at times, I admit it)
- Pages is limited and much less powerful than Word but OK for many light tasks
- Numbers is... frankly, I'd prefer Excel 5 to Numbers 09. Numbers is just a joke compared to Excel. Low power, no VBA, no 3rd-party integration (Essbase, SAP, Magnitude and the myriad of 3rd party plug-ins).
- Outlook & Exchange is top-notch for enterprise use - not sure what cross-platform solution Apple has to offer that compares to Exchange.
- Access is well integrated to Excel and powerful - even though Filemaker is not bad at all a bit less integrated.
