OK, so maybe smartphone notebook applications aren’t the most exciting pieces of software modern consumer technology has to offer. But it’s hard to imagine a smartphone that can make VoIP calls, tell you exactly where you are on the face of the Earth and beat you at chess but won’t let you write down a grocery list unless you care to take out a knife and carve it into the casing. Notebook apps may be bland, but they’re necessary. The iPhone’s native Notes app does its job, but it’s pretty simple — create, sort, type, delete, send to email.
