That was me a long time ago when I moved from Minnesota to California.
That first "winter" in California I was in shorts and a T-shirt while
everyone around me seemed to be wearing parkas.
You get acclimatized.

*Subject:* [AFMUG] Enclosure low temperature
What is the lowest temperature that each of you would normally
expect to see in your enclosures?
The reason I'm asking is that I'm in the process of developing up
a few new products.
To date, all of the packetflux products are designed with
components rated -40 to +85C (I.E way cold to way hot). I'd
like to retain this rating, but I'm running into a minor snag:
For storage, I'm planning on integrating a SD card (probably
microSD) in a socket. I only need a GB or so, and SD card memory
is inexpensive at that range.
Unfortunately, all the reasonably priced SD cards are only rated
down to about -25C or -13F. which are about ~$3 in qty.
"Industrial temperature range" ones which are good down to -40C/F
are available but they add at least $30 to the cost for non-name
brand, and even more for known brands. When you're talking about
a $100 end-user price, a $30 1GB SD card seems excessive - and
probably isn't even possible if I want to meet the $100 price with
some margin.
So, I'm currently playing the 'what options do I have' game. I
hate to ship a product only rated down to -25C/-13F, but I know
for at least a large chunk of my customer base they never see
below this temperature, especially when you add a watt of power
dissipation in the case with the device. Which leads me back to
my original question: What's the lowest temperature most people
would expect to see inside their enclosures.
