I'll bite: Hard science TA's and RA's often repair equipment; it's part of our science. If you want a silver spoon, don't go to grad school. Science is all about dangerous chemicals, semi-safe experimental equipment, and 4am drives down gravel roads in old vans with a nice steep drop on one side. Guardrail? Ho ho ho. Fixing the computers is just the tip of the iceberg. Plus, where else could you get on-the-job experience with a PDP-8?
