Honest question: Is there an app for the iPhone that can edit ODF/DOC/DOCX/ODS/XLS files with the same fidelity as OpenOffice does on the N900? Can it do so while one is offline? Sure, launching OpenOffice.org on the N900 takes 37 seconds (just timed it), but once loaded it is quite responsive, and most importantly for me, full powered.

Other things that I love about my N900 that I have not seen on an iPhone are:
- FMTransmitter (to say the least about its boosted power and expanded beyond the normally allowable frequencies in many countries)
- full python support (including pyQt, pyside, and pygtk libraries)
- Offline mapping apps like marble.
- The ability to run my old Palm OS apps. (I still rely on a couple of them believe it or not).
- Is there an app that can match what MyPaint allows one to do on the N900?
- The ability to hold power decreases over time on all rechargeable batteries. So, being able to replace the battery (instead of the hole device) is huge!

This are things that are really important for me. I haven't seen anything the iPhone offers that is compelling enough to make me switch away from these. A little speed increase is not important if I can't even do these things at all.
