In addition to Phares comment, KIE have also been having a capacity strengthening partnership with Intel (you can read a little about this in the June 2011 issue of CIO East Africa Magazine). So yes, they really have build the capacity, I beleive they are working on more multimedia content to bundle with the books. 

In fact KIE's project was one of the winners of the 2009 Technology in Government Awards (TIGA) in the "ICT in Education sector" http://www.cio.co.ke/Main-Stories/government-ict-in-education-award-winners-announced.html
