But the problems with Excel and general spreadsheet modeling limitations offer such a great opportunity for improvement that would impact just about every business out there. I wish I saw more people tackling this, or I had a great idea to do it myself. The problems I see are around barrier to entry, in that it must be usable in just a couple minutes, simple enough for non-programmers to learn, and equally or more efficient to get a basic model functioning. Otherwise I just don't see wide adoption despite possible maintenance, accuracy, and reliability benefits.
James Kwak has written some smart stuff about this (http://baselinescenario.com/2013/04/18/more-bad-excel/), and I'm interested in what Data Nitro (datanitro.com) is doing.
