O2 XDA Zest or iPhone 3G

[gazfocus]

I have been toying with the idea of buying an iPhone 3G after the Macworld Keynote but I have recently read a review on the O2 XDA Zest Windows Mobile Smartphone.

It looks like it's got a lot of features, and the thing that's swinging it for me at the moment is their are Windows Mobile versions of Word and Excel so I could edit files on it.

Does anyone know if their are any similar apps for the iPhone?

I do prefer the iPhone for its design, the flexability of the apps available, etc, but need convincing that it's worth the extra £100

I had a windows smartphone and whilst there are many more apps its really hard to use, and you have to use a stylus a lot of the time for example to minimise and exit windows which looks really gimpy and is inconvenient.
