It's hard to garsp how useful some iPhone apps are until you've actually experienced them...

Whilst some indeed "only" provide better or offline accessibility to contents which is otherwise available online (eg: Wikipedia or the Zipcar or LinkedIn app), quite a few provide real added value for offline contents. An example is Stanza, a free eBook reader, which none of the corresponding apps for the N900 comes even close to in terms of usability and features. Offline contents is also better when you travel, unless you're keen on roaming internet royalties...

I for one certainly hope that we will see the availability of apps for the N900 improve soon (and no, I don't mean more "unreal housewives" crappola). Apps are a fair indicator of the success of the platform, which in turns is an indicator for how likely Nokia is to continue to invest in it...
