I'm not saying it is a good fit for everyone, but it works out well for me. I do recommend squarespace for individual parts of a self-built tower pc. I spent 120 on a motherboard and on the third replacement spquarespace upgraded me because it turned out that model had an almost 50% failure rate in the first year.
The insurer will calculate the risk of whatever happening, and obviously charge more than likelihood * cost.
So unless your risk is higher than average, you're losing money. And keep in mind that the average insurance taker probably has higher risk than the overall population.
By this logic, nobody should buy life insurance because the insurance companies have calculated their premiums so that they come out ahead. At least on average.
If you flip the statement, it's "do insure against things that can ruin you".
Whether life insurance is worth it depends on what you mean by that exactly. You can insure your untimely death with a benefit for your family, but there are also contracts that are more of a form of investment, and combinations thereof.
While arguably once you're dead, you're, well, dead, so you personally might not care that much anymore, your family might. And for them the loss of one of the primary earners of the family is probably ruinous, so it's reasonable to take insurance against that.
The investment case is different, it's essentially just an investment contract with associated cost. In that case, you're just buying a service (managing your investment, and to some degree insuring against investment risk). The two forms are commonly mixed together, and then it depends a lot on the structure and cost of the contract. YMMV, but I think over here these contracts have very intransparent cost structures and are commonly more expensive than getting a plain life insurance and a separate investment contract (or investing yourself, for that matter).
It is also about making insurance companies fabulously wealthy.
Of course, there's a $500 deductible on that, but the things I expect to happen that would cause me to file a claim on my policy are likely to end up with a lot more damage than that.
My laptop and personal assets I carry when I travel are an entirely different story, a $500 deductible if my duplex burned down or an electrical storm fried every device in my house is pretty acceptable, but that's over 1/3 of the value of the things that go into my laptop bag. Considering I've already had a car broken into and only recovered $200 after my $500 renters deductible a personal assets policy would be well worth it to me if it cost $10/mo.
So everyone definitely needs insurance for healthcare.
Losing a smartphone isn't going to ruin me, but it sure would piss me off to have to fork out £500 or whatever because it gets jacked. Similarly, someone could break into my house and clean it out. Not going to ruin me, but I'd rather not have to replace everything.
The whole point of insurance is collective risk-spreading. Yes, this means that the majority (by value) of people with insurance will have 'wasted' money, in the sense that they purchase insurance without claiming. But that's not what they're purchasing – they're trading off a small, certain cost for the elimination of a large, uncertain cost. That's a purchase of 'certainty' or 'stability' – and it's what they get.
In other words, since you have no reliable way to understand risk and likelihood of a particular event happening, it's not possible to decide if you are at a higher risk than average.
Go talk to an _honest_ insurance broker (not some State Farm or other company you see on TV commercials) or better yet a financial adviser. You should reserve an insurance claim for catastrophic issues only. You should also have max deductibles. Forking over 500 for a lost iPhone is a MUCH cheaper deal than paying insurance premiums for that coverage and then the INEVITABLE rate hike because this claim appears on your CLUE report.
I made the same naive mistake as your assumptions when I was young. Lost a 1k watch, made a claim, went about my jolly day with my nice check for $750 (250 deductible). 1 year later when I go to buy a house I am surprised by how much my insurance rates are. FOUR years later after that claim fell off my CLUE report my premiums went way down. I paid the insurance company more than the $750 I got from them.
I was lucky in that my neighbor was an insurance broker and told me low deductibles are taking advantage of suckers and the lesser fortunate who are scared into these policies. What he advises most of his clients to do is take the highest deductible they can, then put aside that amount of deductible in some low earning liquid account. Now when you have an accident you "pay your self" and keep your insurance rates low.
Don't be a sucker.
I'm in the UK, so I can't help but assume there are differences in the insurance market. I have a comprehensive insurance policy that covers buildings, contents and accidental damage, and that covers things like smartphones too. Despite a couple of previous claims for stolen and damaged electronics, the rates are pretty good. The marginal cost for accidental damage is minimal.
But yes, low deductibles are a sucker's game.
Don't be a sucker.
As a counterexample, for all but the richest people having catastrophic health insurance is a good idea.
If you can afford to replace the item yourself you can instead spread that risk over time (and multiple items) by essentially self-insuring.
I absolutely agree you should buy insurance for "large, uncertain costs", but a smartphone or laptop is not that for a lot of people.
Healthcare and liability (auto, homeowners/renters, etc) are two examples of actually "large, uncertain costs" for most people.
Consider also the overall effect if you invested the premiums instead of paying them.
I know when you're young 45 years seems like it'll never happen, but if you're lucky it does.
Have tons of cash? You should still probably look at a cheaper plan with a super high deductible.
In fact, my laptop is a $500 one I bought 2 years ago for travel use and didn't want to be too upset if it was lost/broken/stolen.
My previous one was 10 years old and was a bit heavy :-)
You are not living in reality. Most of people live on credit and can't afford to pay for things in full.
Especially not $500 laptops "for travel".
If I had to buy such on credit, I'd opt instead for a $150 machine from a pawn shop I could pay in full.
Not everybody on the planet needs something svelte and sexy, but for those of us who work on their machines a $500 POS doesn't cut it.
I did everything on that machine up to and including playing TFC via Steam. It ran an IRC client, Chrome, Firefox, VirtualBox for Windows, and my xterm w/tmux. I don't know that I'd give up my rMBP for it, but I did a lot of work on the chromebook.
As far as a developer machine goes, a $300 special 14-15" screen plus $200 of RAM+SSD would probably be fine for 99% of what I do. This likely doesn't work for those who need Photoshop, do video editing, or need to rebuild their OS (rebuilding world in FreeBSD on the thing would have been a bit much). If you're slinging JS, Python, Ruby, Erlang, Clojure, Java or something similar and you can't get by on 16GB of RAM and a 128GB SSD, something is atypical.
I use a desktop for dev built with about $600 in parts from newegg, excluding the display. I do get a bit spendy on the display, as that is the most bang for the buck value to me. None of the high end laptops have a display large enough for dev for me. Portability and dev are at odds.
But this thread is about insurance to protect against the loss of a high end laptop. I presume that someone doing serious computer work is making enough money that they don't actually need insurance to cover the loss of even a high end laptop, and the premiums hence won't be worth it.
