I know that this is a arm based list - but - to play devils advocate - and
not to aggravate
everyone on this list [1], I must admit that I'm having an issue seeing the
value proposition here.

Take a a look at this Intel NUC
<http://www.amazon.com/gp/product/B00HVKLSVC/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1>
Drop in a low-cost SSD  (Crucial MX100 120Gb
<http://www.amazon.com/Crucial-MX100-adapter-Internal-CT128MX100SSD1/dp/B00KFAGD88/ref=sr_1_fkmr0_3?s=electronics&ie=UTF8&qid=1412707060&sr=1-3-fkmr0&keywords=crucial+mx100+120gb>)
and you've got
an x86 system + enclosure + power supply (brick) - that you can stack (if
you wish to).

Given that you can run your choice of OS and take advantage of Docker
<https://www.docker.com/> containers... why mess
with ARM based systems.   What are the advantages - especially considering
your time investment.

OR

to continue to play devils advocate, you can spin up a 7x24  f1-micro
instance <https://cloud.google.com/compute/#pricing> for about $8.xx/month
with the 40% discount you get for running it 7x24/month.   Understand that
there is no committment
and you have no power or UPS or Air/Conditioning (A/C) bills - and no,
up-front, capital equipment
costs.[2]

So, if I, again, playing devils advocate, compare 5 ARM based systems at
$100/system, compared
with two Google Compute Engine (GCE) f1-micro instances for one year:

ARM hardware         GCE  VMs
5 * $100                    8.12*2 * 12 = $194

How about for 2 years:

ARM                          GCE
5 * $100                     $389

How about for 3 years:
ARM                          GCE
5 * $100                    $584

4 years:
Whoops - time to replace that "old" ARM hardware.   Oh - and BTW the cloud
based VMs will
very (extremely) likely have gone down in price and may or may/not be ARM
based!

Yes - you have to pay for "virtual" disk and bandwidth etc.

But .... I'm having difficulty seeing Roberts' cost/benefit to running ARM.

As I said,  please feel entirely free to push back at me.   I'm not trying
to troll this list - I think
its very interesting and beneficial and I applaud every contributor.

[1] as you guys know, I'm already providing some support to the list
members in terms of
a means of providing some download facilities at opensxce.org.

[2] the other alternative is an Amazon Web Service 1 or 3 year reservation
on a t2.micro instance.
And don't forget the AWS Free Tier
<http://aws.amazon.com/free/?sc_icountry=en&sc_ichannel=ha&sc_idetail=ha_en_c_cta_112_1&sc_icontent=ha_en_112&sc_iplace=ha_en_hero_cta&sc_icampaign=ha_en_FreeTier&trk=/>
which
gives you a micro instance with storage/bandwidth
etc. etc. *free* for one year.
