Off the boil

Had a very long parents' evening tonight with Year 10's, a tough crowd.  My roughest encounters weren't with the kids who weren't going to do well on exams.  For the most part, their parents had realistic expectations for them and knew their child's strengths and weaknesses and behaviour issues better than I do.  It was the boy who could be doing so much better, but who can't be bothered to do a good job on his homework or to revise for tests, mostly because he spends all his time playing on his Xbox or whatever handheld machine kids have these days (it's been a long time since Donkey Kong).  These things are evil.  I now sit across from my DH who is sitting slouched and crouched over our blessed new iPad, playing this obsessive game called Angry Birds.  While there is some Physics in it (trajectory and elastic potential energy), I cannot see the appeal.  What is it with boys and these games?  I like a game of scrabble and quite enjoyed a go at the formula 1 racing game, I do not feel the urge to hit RESTART over and over again to get to the next level.  What should that parent do? What should I do?  The parent decided that a ban on games would be necessary until after mock exams (oooh, a whole week away - too little too late?)  Husband? Better keep drinking the wine.  I am wearing my new black boots...
