hmm, gamers use "QQ" (due to the resemblance of tears coming from eyes), often in the context of "less qq, more pew pew" to communicate a lack of empathy.
Wikipedia has an entry for the term "computer rage": http://en.wikipedia.org/wiki/Computer_rage , which seems to have a certain amount of acceptance in the academic community, but it doesn't seem to have the ability to catch on (not going to say the m-word, not going to say the m-word...) the way "road rage" or "workaholic" do.
Notice that discussing ways of reducing this frustration are not part of the discussion.
bob was pretty tek-emo after his macbook battery exploded, his ipod hard drive fragged, his gmail accounts wiped, his facebook profile vandalized, and his WoW account stolen.
I'll raise the possibility of recycling the old "e" prefix, once more.
e-rage
e-despair (e-spair?)
It might even be applied in initially unanticipated ways. E.g. e-lag (a takeoff of jet-lag): That tired, time-shifted feeling you get from 2 am "global" meetings, without the necessity of actually getting on a plane.
It also can be taken to refer to things electronic, in general. Thus it might well be retroactively applied to activities such as programming the VCR clock, and the like.
Whatever the phrase that sticks, an important component will be its easy pronunciation. "Road rage", "jet-lag". Simple and with preferred syllabic structure. For more on that, google some of Theo Vennemann's (linguist) work on optimal syllabic structures (I assume its out there somewhere).
