iA Writer for iPhone just came out. 0,79€ for both iPhone and iPad (that I plan on upgrading to iOS 5) apps? Instant download!
I haven't used it intensively yet but one thing that really bothered me (or at least surprised me for its lack of common sense) is that taping the "+" icon to create new document does just that. And I mean only that: it adds a new .txt file called "Document" but doesn't open it.
In what context would you want to create a document without the intent to actually begin writing in it ??
I personaly don't plan on filling my iCloud space with empty 0.1kb-sized documents.
