Just an observation as I have all 3 as well - (ok, so I'm an app junkie and still look for perfection) - You need to take ALL reviews with a grain of salt!
1. The iWork suite is easiest to use provided you have a non-Microsoft leaning - they follow the Apple thoughts closely and are indeed easy to use if you are familiar - if you are from a heavy PC/Office background, it may take thinking outside the box to figure them out.
+++iWork is real simple to use. I have both Microsoft and Apple learning. Ive been using Apple for about 3 years now. But what I like about it is the simplicity of creating formulas in Numbers.++++
2. NO PRODUCT can do everything the desktop apps do yet (maybe never?). Some things just don't work - don't show up or work different (call it 70-80% compatible) - just accept it and they are all good.
+++Agree.+++
3. Plan for heavy formatting to take the biggest hit, then special add-ons like Tables, embedded graphics, etc.
+++True+++
4. Plan to try a couple of different input formats - they seem to do better/worse depending on the input version (i.e. Word 2003 vs. 2007) - no idea why, just accept it and zero in on the version that works for your stuff.
