The iPhone suggests Web 4.0 with EverNote, which uses geo-location ToDo list entries, i.e., when near the location of X, remind me to do X task.
EverNote captures and indexes all your media, handwritten, text, web and even reads photos, looking for text. A screen capture of an email on your iPhone (hold down both buttons briefly), for example, when then transferred to EverNote will be read and indexed. All entries are cloud synched. It is a major organizational tool and the genius behind it is adding new bells and whistles every few months.
Happily, another powerful data/document organizational tool joins my TopTen Software List, along with X-1 and NeoPro for Outlook. I could not sit down at my desk without. Nothing even approaches the List unless bug-free (or have eager upgrading &/or support), have a well-designed user interface, and innovative functionality. This eliminates all Microsoft products prior to 2008; they'll be on another list. That List is now led by Windows Home Server, but this diatribe is saved for a really lousy rainy day.
Back to Web 4.0. As an ex-photographer, both scientific and commercial (& some art here and there), I've been looking at digital organizational tools for twenty years: http://tiny.cc/PC1985DEC
I've been craving this for awhile: http://tiny.cc/DCHCNET
Maybe "Web 4.0" isn't the right acronym. It is a meta-structure as Windows is, combining multiple functions in an efficiently accessible manner.
These tools are just starting to appear, way behind the actual capacity of the PC to perform them.
Since each will almost inevitably be of proprietary format, 95% of said formats rarely lasting longer than half a decade, we will require universal access to our various indexes, an Indexing Indexer, much in the vein of social network conglomerators glued together with the lowly macro.
I'm not holding my breath! "Hazel" for the Mac hints at this, so along with Evernote and Jott, Web 3.0009 does exist. In the meanwhile, archive output everything in TXT or PDF.
