Odd that Cuba appears to be supported, unless shipments to there
are restricted some other way

I can't figure out the rationale of how a particular country is included.
You might expect very few, if any, requests from Bhutan and more
than a few from England (England ? Great Britain, please)

Yes, that was how I read it too. Sorry, my reply was ambiguous.
The 'snubbed' feeling was meant as a general comment to those
still on the list, although historically local distributors haven't been
helpful with samples

Maybe they figured out a way to identify the people who were ordering
samples to sell on ebay?

Are people really dumb enough to buy samples on ebay?

or they decided that the lost legitimate sampling opportunities (ie: to real 
engineers designing real products) was more costly than what they would end 
up giving away.  Note that a real engineer, especially working for a big 
company would probably have to jump through several hoops to get the $7.50 
s/h paid for sample orders (the bigger the company the bigger the hassle).

I can imagine people will buy chips on ebay. Especially if they just 
want one of a chip and  can't get a free sample for some reason (where 
they live, sample quota run out, simply aren't aware free samples exist 
and so on) and want to avoid the small order charges/ minimum order 
sizes that the big vendors give individual customers. How would the 
customer know where the ebay seller sourced the chips?

Not really.

Nowadays, I pretty much insist on isolated thermocouples.  They can 
be priced reasonably if you work with the manufacturer and you are 
buying in at least hundred lot quantities.

One approach I tried in years gone by was to use an isolated dc-dc 
convertor and an opto-isolator: the thermocouple reading was 
digitized, then sent over the opto-isolator.  It worked but its not 
cheap.  Figure on at least 10 bucks extra cost per isolated channel.

Oh Gosh! Thanks for the tip! I have checked my account info, and as Ireland
is no longer supported they set my home country automatically to Australia!
I guess it is simply because that is the very first one on the supported
list. So that's why it showed $0 fee when I have checked... (I have not
looked at my profile before as I never could ever possible imagine that this
kind of thing could happen...)

Real engineers designing real products don't choose components on the basis
of availability of free samples. Non-availability (in small quantities with
short lead time) can be a factor but not having to pay a few dollars for
them isn't. 

For simple components with a mechanical aspect like switches and connectors
evaluation is mostly just looking at them and putting samples in engineers
hands could be a worth while loss leader. The effort required to evaluate

As a college student, I sampled lots of PICs, but I also learned with them
in my spare time. Starting with the 16F, going to 12F and 10F for small
projects, then I started playing with C18, but never made it to dsPICs.

Then I finished school and got a job. I was given sole authority on the
design of my first project. I chose a PIC. Because Microchip sent me free
samples, I became familiar with their product line and use their products as
a hobbyist at home. Now I use them as a professional at work.

I know this is an exceptional case, but their free samples got them another
customer.
