Only way I would be worried about is if you sell them but that isn't the case as you said.

One of the specs of a HDD is the maximum altitudes for reliable use, and transport, around 35000ft for transport I think.
If carried in hand luggage, any HDD is fine as the cabin pressure is equal to around 8000ft. It's also fine in the luggage hold if that is also pressurised, but you may not know if it is or not. Any airline that carries animals will almost certainly heat and pressurise their luggage hold.
About the aircraft, the cargo hold is pressurized.
The air gets pumped from the front of the pax compartment to the back and there are vent valves/holes on the side of the floor. When having a leak or such those can literary blow wide open so that the air pressure above the floor is the same as under it.
For storage IMHO it would be best just to keep the SD cards safe and have plenty of them. All storage devices can fail and lose everything, but probably the cards least of all. They are the safest bet overall, and the cheapest option too.
What would you think of such device link

A quick search says that they are €299,- so around £255,- without a hard disk. Netbooks are close to the price but it's not that easy to swap disk but you can use external drives of course.
Todays 2.5" 500GB harddisks are €75 (£65) making them €0,15 (£0,13) per GB, you can't beat that with SD cards.
Since you can swap harddisks that means you can first save the SD card on one and then on another harddisk so that you always have a backup.
Of course it depends on how many photos you make what is cheaper but with holidays I found myself shooting around 4gb a day in raw... might be better to switch to JPG with the holidays but then again RAW can give you better results...

An advantage of SSD over HDD which hasn't been mentioned is that SSD is OK at high altitudes where HDDs are not.

I'm also wandering why people take a laptop with them for the simple reason to back up the flash card. Any reasons behind that besides that you may lose the SD card?
There are image tanks on the market, which might be all that you need.

Lemmy have stated the other options and the 70-200 lens might be what you want, with F/2.8 you will have iso400 instead of iso800.

The 18-250 covers almost everything and if you like the lens then that's the only lens you really need but I can see that you would want a bit more quality or lighter weight sometimes.
In most situations a 17-70 lens is all that you need so depending on what you want to shoot it might be interesting too look for that lens.
Or else the kit lens with the 55-300 is also a fine combination depending on your need and if you want to take your 18-250 with you or not.

If it's a hardware problem it wouldn't solve it though but an update would not change your situation.

I my view the best thing they could do is to give us control on how the user interface is built up.
I for one would love that my K20D would default to ISO100 after a power cycle, but it doesn't. It stays at the setting that you used before power off. You can disable that it saves this setting but then it defaults to auto ISO

The part I would be the most worried about is the alignment of the mirror, it's quite a preciese piece that part but that has being in a SLR for a long time.
Like said most features now a days is software, no components are added.
What I do worry about is that those software slows it a bit down but to be honest it's still very fast so maybe I'm worrying too much here.
The feel of the Pentax is one of the best in every class so they got that right. Also on other forums and here you notice that Pentax camares are quite durable, never heared of a button that doesn't work.
The most common problems with Pentax is the sensor besides that there are the few unlucky ones but it isn't that bad.

Try a firmware upgrade then atleast you know it isn't that, if you still have a problem send it back to the shop or to Pentax.

to do in camera B&W properly would need a way to change the filter in front of the sensor.
The resolution will increase with 3X for red and blue colours and 2X for green when doing that.
You could still shoot colour if you like with the help of filters.
So first you place a red filter and take a photo, then a blue and a green one, you could even use more I believe but that's enough to get an accurate colour image in the end.
Not usefull for portrait but it can be used for product shots and maybe landscapes.
You will end up with a sharper photo this way then with a Bayer array.
