"Developers Spend 13 Hours/Week Administering Their Desktop.".
That seems like an awful lot, 2 days a week on "administering"? Is this real data from desktop IDE users, if so then this is clearly a huge problem. What kind of things are people spending the 13 hours on each week that is saved by moving to a Cloud IDE?
I could see overhead if developers were constantly swapping from project to project to fix bugs and each of those projects had different set ups in terms of where the source code was stored, how it was configured etc.
I can't speak for other companies/languages/setups but using one of Eclipse/Netbeans for Java with Maven and SVN/Git is pretty low overhead in terms of configuration for me. For PHP we use SVN, SublimeText and pre-defined build and deploy scripts, which also do not have many pain points.
Genuine question: where is the 13 hours spent each week?
