'puters themselves ain't bad, but lotsa folks do themselves no favor in failing to learn the basics. Ya gotta remember; its a technology barely out of its infancy. The biggest problem really is the amount of end-user control over the things. While hardware failures, design errors, and incompetently constructed software play a large part in frustrations, far and away the leading source of difficulties is the user. Either the user does something ill-advised, or fails to do something which should be common practice.
Gotta pretty much agree with mosta the gripes about tech support, though; all too often, even vendor tech support is pitiful. Even there, however, there is another factor to consider. Clueless, outsourced, cubicle-bound, incapable-of-independent-thinking, communication-challenged droids aside, the user often is the bottleneck, providing the otherwise competent and willing tech spport person with incorrect and/or irrelevant information to begin with. I know lotsa tech support facillities are all but useless, but those which are competently staffed can do only what you let them do, much as a 'puter will do only what you tell it to - Garbage in=Garbage out.
I can tell you from personal experience just getting the necessary info from the customer can be a real challenge, closely followed in degree-of-difficulty rating by getting the customer to do exactly and only what you say to do.
And all that aside, things are better now than they were 5 years ago, and ten years ago, you were pretty much on your own; if you couldn't figure it out yourself, there pretty much
WAS nobody to call. Twenty years ago, only geeks had personal 'puters of their own, and 30 years ago, anyone who had a personal computer built the thing.
Say whatchya wanna about Microsoft, IBM, and Intel, they were the delivery room staff at the birth of the boom. And believe whatchya wanna about Apple; Macs can and do crash - spectacularly - and are increasingly vulnerable to external attack, an inevitability of increasing market presence. The same goes for "Alternate Operating Systems" and "Alternate Browsers" as well; as they become more common, the entertainment value they provide to evil-doers goes up right along with their popularity.
And remember - to err is human, to err consistently and in precisely the same fashion requires a computer
