The desk with or without PC is the easy part...in the end the will both hold PCs (or equivilant) it is the way the world is going...Both of my kids (K and Year 3) use computers at school and also at home...
The more difficult part is the rebuilding the "bridge"...I sometimes "teach" a question asking technique to our employees involved in selling (building a relationship) that might help...it works like a champ with my wife and generally helps her to "believe" that what I want is actually her idea without me needing to argue about it...VooDoo or Jedi Mind Tricks ??? maybe so but it works...
Good Luck!
