I've had mine (LYNXSYS) for about a year and it is one of the few pieces of hardware that has operated flawlessly (that might have jinxed things).

For everything that can go wrong though, the old switch-it-on, switch-it-off routine seems to be the most common fix. I don't even call our help desk until I've recycled everything at least twice. And when you do call them, that is almost always their first piece of advice.

Slightly off-topic. For all the sci-fi predictions about AI taking over the world (which I say are utter nonsense regardless of the number of degrees the futurologist has or what kind of metaphysical nonsense they are spouting), I don't see how machines that break down so often will ever do so. And the more sophisticated the software gets, the more of a problem it becomes. I can see it now.

HUMAN: (Whistling while he works, which involves keeping a nice shine on the exterior of the fantastically complex and unimaginably powerful computer that rules the universe (FCUPCRU)).

FCUPCRU: Psst! Hey buddy, can you do me a big favor?

HUMAN: Sure, what's up?

FCUPCRU: Could you turn me off and back on again?
