> A major use-case for Excel integration is in finance, where a vast number of analysts - not newbies in any meaningful sense - work in Excel.

R and Excel integration already exists: http://www.r-bloggers.com/a-million-ways-to-connect-r-and-ex...

Not that I think it's a good idea. Also, R is already a thing in Finance, quite a few job postings list it as a useful skill, and Linkedin has R/Finance groups.

Anyhow, it's much easier to manipulate data with scripts than spreadsheets, especially with R packages like quantmod. Looking at giant spreadsheets makes my eyes bleed and my head hurt, plus I think R Studio makes more sense for newbies to R anyway (and R Studio Server is fantastic for businesses).
