@kfield ...buying a car well into a long production run is the way to go because they've had time to work out all the kinks...
But this is not the attitude that marketeers love in their suckers customers. They attempt to sell to the yuppie mentality that demands the latest status symbol, even if not the greatest due to bugginess. Cars, software, whatever - all the same.
-- Food for thought -- Switzerland, where being part of the military is Manditory, and keeping a gun safe in your home with an assult rifle locked in it is Manditory, and where Fire-arms training is Manditory, and where it is one of the few european countries with an economy where companies are moving there, also has Manditory Health insurance, a minimum wage of over $20/hr, and a longer life expectancy than the US -- There you have your choice of any plan that is approved by the government, can use it at any public, home, or private provider -- The democrats and republicans each should have ate a little crow and seriously looked at this approach.
Good things about obama care - enough people in the pool in the larger states that the insurers pay about 30-40% of what a private plan pays for most prescriptions. This leaves more money for prevention and treating other conditions
Bad things that need work -- only a few providers take the plan -- more are joining but this was not well ramped up in advance. Even in major metro area's people are sometimes having a 4 hr round trip to see a specialist on the plan. This is very similar to the situation the veterans returning from overseas face -- they too must travel far in the VA system and go through much red tape and lost time from work for covered treatment. Other bad things -- not all hospitals meet the plan standards -- so one may have to travel a distance for an ER visit to be covered.
@sanjibA I think not buying a product when it first comes out applies to almost anything. Two years ago we bought the last model produced of the Ford Escape before the new models were introduced. While our Escape has been running flawlessly during that whole time, I've since heard of two major recalls with the newly designed Escape. I have my mechanic to thank for this decision - I asked for his advice and he said buying a car well into a long production run is the way to go because they've had time to work out all the kinks and there is a supply chain in place for spare parts.
Having designed alarm and safety equipment, the most important principle is "Keep the design simple and conservative." It is far better to push a button to reset an alarm than depend on some sexy cutesy-poo device that adds needless complexity at the cost of reliable operation.
One other point about CO detectors. Since the sensing element must be replaced every few years, why not have it plug into something like a tube socket. This would be far more efficient and econimical than having to chuck an otherwise perfectly good instrument.
Actually, I did contact them sometime later. The person there then had no idea what I was talking about and said I could do what I wanted with the idea. I really didn't want to patent it; I already have a few. But, selling the idea for a few quick bucks sounded right to me. Well, I did make some contact with a proposal to that end; however, I heard nothing. I would still be willing to present the idea for a fee; and if thought viable just sell it for a final fee. I don't care too much whose name ends up on some patent. So, do you here me out there Google? You seem to be able to find out almost everything about anybody. Just give me a heads up with contact info!
