Ok first of all what is the difference between these two products?
Secondly are the development skills interchangeable between Server 2010 and Foundation 2010?
And lastly in terms of job market, when HR department writes "Looking for Sharepoint developer" do they mean developer for Sharepoint Server (MOSS) or Sharepoint Foundation (Services)?
Note: Working with SP Foundation would be better in my case because Sharepoint Server 2010 brings my computer to its knees with only 3GB RAM. Sharepoint Foundation is it a good starting point or would you suggest going with Sharepoint Server?
