I Seriously Don't Know Where He Gets It

Spencer has developed a love for playing on the computer. He will walk over to either Alisha or I and just shout "Puter". He's not really asking, a rough translation of these two syllables is "I'm ready to play, someone turn the computer on NOW!" Once the computer is on he knows how to open a web browser, get to the Playhouse Disney website, and select his favourite games to play. This, in and of itself, is quite good for a 2 year old. He knows his way around a computer at a very early age. He loves the Handy Manny game and makes all the tools make funny noises. When accomplishes this he turns and looks at us with the biggest grin, it is very cute. He certainly takes after me in that regard (both being cute and good with computers) but he has developed a habit that I find quite extraordinary.
After a few minutes of playing games Spencer will sometimes become frustrated because a game has become too difficult or because he's opened something that stops him playing. When this occurs he shouts "Stupid Puter!" and starts to get angry. At times Alisha or I have had to stop him from pushing the computer on the floor. I don't know where he inherits such behaviour. I was certainly not like that when I was a child, and I'm not like that today. All of my family are always calm and collected and never shout at, or abuse, inanimate objects such as computers, vacuum cleaners, etc. I imagine that this is his mother's doing and has come from her side of the family.
On a side note, the new hard drive in my Mac seems to be working fine. I've found that thumping the table in frustration does not help computers. Imagine that...
