Seriously, you can put your inner Apple fanboy to rest. I was just using the iPod sync cable as an example. If you don't like me putting Apple on the spot then just replace all instances of "Apple" with "Sony" and "iPod sync cable" with "Memory Stick (MS)". The same circumstances apply.
The point I was trying make is, if manufacturers made an effort to standardize trivial components like cables and interconnects then everybody would benefit.
Example: Theoretical laptop power supply standard - a standard wall-wart for all consumer level laptops, a standard for voltage, maybe a signal line so the adapter could read a hardware level setting for required current from the laptop and adjust accordingly, universal connectors for airplane car and house power like the Dell AC/Auto/Air Power Adapter, and a magnetic connector for the laptop like the MacBook Air because that's just too awesome not to have.
For proof of concept, Dell has already switched over to standard adapters for all Dell laptops sometime around the Inspiron 6000 generation and I'm positive Apple has been doing this since waaaaay back when OSX was introduced so isn't this feasible for all consumer level laptops?
Imagine buying a laptop and omitting the cost of a power supply because you already have a few lying around (even if your laptop was from a different manufacturer) and the waste generated by the wall warts left over from previous laptops. That would be a huge selling point, not to mention how much it would simplify the manufacturing process. Of course, not everybody would buy into it but they would be at a disadvantage to their competition if they didn't.
I'm so glad cell phones are finally being standardized. Now I know that, if I buy mini to micro USB adapters for my phone. I'll be able to use them on future phones, ear pieces, as well as all the other stuff I charge off of them. No more carrying around 5 different wall warts all the time.
Why are HDMI so expensive, IDK, look up the spec and see what makes a HDMI 'special'
