The Terrafugia Transition may not be as "attractive" but it's far closer to being an actual product that people can drive / fly. There are big tradeoffs when you add road capability to a light plane - it adds a lot of weight. The Aeromobil also appears to be shooting for something that can legally be considered a light sport aircraft in the US, so if it weights "only" about a thousand pounds, that gives you almost no capacity for passengers and fuel. 400 mile range is not a lot.

This is just cramming two ports into one space (in the example, SD and USB) so you can add more functionality to the sort of thin & light products that Apple is obsessed with. No need for a "special Apple cable", since the whole point is that it can accept several standard interfaces.

One maddening thing that people seem to miss is that the flickering from PWM is NOT at the same frequency as the PWM.

• if you are driving LEDs at 100% brightness you should see no flicker from them at all, since they are constantly on.
• at 50% brightness, you are switching the LEDs on or off once per cycle.
• at 10% brightness, your LEDs are only switched on once per ten cycles.

Say you are running PWM at 100 hz. at 50% brightness, your light is flickering at 50 hz. At 10% brightness, your light is pulsing at 10 hz.

This easily explains why LED flicker can be visible (to those sensitive to flicker) even when PWM is hundreds of hertz.

Speaking personally, I suffer from migraines and am exceptionally sensitive to flickering light sources as a trigger. This happens even at frequencies much higher than those that trigger photosensitive epilepsy. Flame away if you think this is psychosomatic. I wish.

That said, I have noticed very few LED-backlit monitors that suffer from flicker issues at normal brightness. And I *can* detect flicker from many LED sources such as brake lights, traffic lights, and flashlights that use PWM, and especially things run off mains power at 60 hz (intolerable) or rectified "flicker free"120 hz (still pretty intolerable, since the lights still cut out at the crossover point).

I'd also point out that migraines are pretty distinguishable from regular headaches, and (for me and many) also have a significant nausea-related comment, so while the OP may be sensitive to flicker, his symptoms sound more like normal eyestrain.

As an Arizonan, I must say that you are incorrect - as of last year, concealed carry permits are no longer required. Anyone over 21 who is legally allowed to own a firearm can carry it concealed, with very few restrictions. This has been a contentious issue in the state and I'm sure this latest incident will not make it any less so.

If by 'they', you mean congress, the 2007 measure set efficiency standards that effectively ban standard incandescents. It doesn't force you to use CFLs over LED or any other technology. For most people, LED bulbs are simply not an affordable replacement for standard home lighting. Yet.

A real outdoor GPS (not a car-nav unit) will have substantially better battery life and be reasonably waterproof and shockproof. It also probably won't be dependent on a touchscreen that is impossible to operate with gloves or as soon as your hands get wet/cold. It may have a screen that is actually readable outdoors. Many GPS units take standardized (AA) batteries so extended trips without recharging are relatively easy.

An android phone will have a bigger, more colorful screen and a more open/versatile OS, and it will undoubtedly be easier to load whatever maps you want on it, rather than vendor-approved, possibly expensive ones. Without some sort of additional protection, though, the device will break the first time it gets dropped on a rock or rained on. It'd be more suited to city and car navigation than camping and hunting.

No love for mac users, eh? The only thing that loads in Safari is the title bar.
