I've been using an old iBook G4 running Tiger as my field computer for writing/surfing on the go, but now that security updates for Tiger appear to be a thing of the past, I'm thinking about just getting an iPad with a keyboard as a reasonably cheap alternative to buying a shiny new laptop. I've been using Journler, but I guess now I'll have to select a new iPad-friendly journaling app, preferably one that exports entries to RTF format. Any favorites or recommendations?
