I was also quite curious as to what "assisted GPS" means on a page that
is supposed to be the technical specifications of the device. Two words
is kinda vague. Either it really does have GPS or it doesn't. I thought
that is why the plastic case, because the GPS antenna MUST be somewhere
it can see the sky. The satellites are around 16,000 miles away and line
of sight. Any reflections, like operating a GPS receiver in a building
so the signal must bounce off something to get through the windows makes
the GPS fix very inaccurate because it's an analog system running on
timing and phase relationships between multiple signals. In a car, you'd
have to provide iPhone some kind of dash mounting bracket so it could see
UP into the sky, not with the car roof blocking the RF raining down on
it.
The temperature range is probably dependent on the LCD's capabilities,
not the phone. Too hot, the display turns black as the crystals melt.
Too cold and the crystals are so sluggish the display looks like slow
motion and will actually "freeze" at some low temperature. But, I
thought we'd gotten over most of that issue, especially in the cold.
Maybe they're afraid of the hot glue holding the cables on inside the
case melting.
Has anyone had iphone troubles because they forgot and left it in a car
in the hot sun? What did the display look like before it cooled back
off?
I cannot imagine ANY portable device needing a volume limit. All the
damned things, including my Nokia N800 Linux tablet, need MORE
AMPLIFICATION so you can hear it in a noisy place. Every one of these
devices needs a hardware-based audio compander (compressor-expander) to
provide proper audio levels because the source material is either driven
into distortion or is so low you NEVER have enough volume control range
to bring it up so you can hear it. Even internet broadcasters do a
HORRIBLE job of watching and adjusting their encoding levels to ensure
peak audio output without overdriving their encoders. Very few use
companders at the source, so the devices desparately need them at the
end. One of the reasons I didn't upgrade N800 to N810 is N810 has LESS
speakers, mounted on the sides, than N800's front mounted on either side
of the display. Sitting close enough to watch it, there is noticeable
stereo from the speakers. I don't sit on the side, where the N810 audio
comes out. The other reason was the loss of big SDHC memory cards, going
to a single microSD limited to 8GB. N800 has lots better storage.
