Maybe the arrival of the new Apple cloud-based MobileMe (with file and music sharing, etc.) will see the revitalisation of iWork?
Apparently, from April, the basic MobileMe product is to be free of charge (about time too, given that Google and DropBox already are) with new functionality planned - largely with iPad users mind (limited local storage).
iWork 09 is really starting to look creaky next to PowerPoint 2010. I still prefer using it but it lags so far behind in terms of handling layers (PPT's killer app!), graphic flexibility (shapes, shading, diagrams), image manipulation (photo editing, proper cropping tools, advanced alpha, etc.), clumsy file sizes, inability to save as pptx for PC users, etc. etc. So NEEDS to be updated.
But so does MobileMe. It is laughably out-of-touch (does Steve Jobs know that it still uses Flash to upload files to iDisk?), it is slow, buggy and idisk is not only unstable but anything you put on it becomes invisible to Time Machine.
So, maybe they will kill two ageing birds with one Apple?
We'll see.
