You can sit by me! I had a great weekend and W slapped me down before I got home.
I am sure you know H better than me and you may be right on the computer meaning something. I wouldn't read into it too much, it could be a selfish act to make him seem the better/ cooler parent.
At 15 that stuff seems awesome, and it's a long time from now, but in a few years when they are older it will be more important that you were there, the memories you make and how they feel with you. Because in truth in a week that computer could be replaced by a million new and better ones.
The person that you will spend the most time with in your life is yourself, so make yourself as interesting as possible.
