                            features that have attracted me to ARMv7
                            are:<br>
                            <br>
                            1) Power consumption<br>
                            <br>
                            My ROI on power savings was 15 mo. with the
                            Cubieboards over my current Intel SFF
                            boxes.  And along with that is lower UPS
                            requirements and heating.  I have 5 boards,
                            plus drives powered from one USB power
                            supply.<br>
                            <br>
                            2) Board size<br>
                            <br>
                            With boards the same or smaller than a 25"
                            drive, I truly have an appliance that can be
                            placed anywhere.<br>
                            <br>
                            Now there are few ARMv7 boards that meet my
                            exacting requirements: 1 or 2 MB ram
                            (depending on appl), 2+ core, and SATA
                            interface.<br>
                            <br>
                            If all I have is USB, then I get the
                            USB/SATA adapter cost and powering thrown
                            into the equation.  Also a board that has
                            been moved into the mainline kernel and
                            distro support.  RPi stands out as being a
                            pain.  4-port LAN features require kernel
                            customization.<br>
                            <br>
                            I was talking with one manufacture that was
                            meeting my main req at $15/board.  But they
                            went for a mass-market target and dropped
                            the DIY one.  I will be talking to them
                            again next month. But their board is not in
                            the general sunxi effort.  Yet.

                                  rgb(204,204,204);padding-left:1ex">
                                  The big problems I have with the
                                  majority of the development boards
                                  are:<br>
                                  <br>
                                  1) Memory<br>
                                  On 32-bit ARM, the RAM was always
                                  limited to 4GB, which would be find if
                                  there were a significant number of
                                  devices available that ship with 4GB
                                  of RAM (minus the various necessary
                                  memory holes). But that simply isn't
                                  the case. I can think of hundreds of
                                  devices with <= 1GB of RAM. I can
                                  think of only about 4 with 3-4GB of
                                  RAM (of which at least 2 are
                                  deprecated and unavailable), including
                                  ARMv8 which is not limited to 4GB. And
                                  two of those four are laptops.<br>
                                  <br>
                                  2) Memory Type<br>
                                  We've been being told since forever
                                  that the main reason why ARM devices
                                  don't come with DIMM sockets is
                                  because they are 32-bit and DIMMs have
                                  64 data lines. Well, with ARMv8 we
                                  have those 64 data lines, and yet
                                  there are precious few devices
                                  available featuring DIMM sockets for
                                  memory. There are in fact probably
                                  more dev boards in SODIMM form factor
                                  than there are those featuring DIMM
                                  memory sockets.<br>
                                  <br>
                                  3) Board Form Factor<br>
                                  There are painfully few ARM boards in
                                  *TX form factor. Off the top of my
                                  head I can think of a total of 5, of
                                  which one is positively ancient and
                                  probably no longer available (Atmel,
                                  IIRC), one is deprecated, the
                                  manufacturer of the 3rd appears to
                                  have gone bust, one is on the
                                  underpowered side (VIA APC) and the
                                  5th is exorbitantly expensive (at €800
                                  there is no incentive at all to buy an
                                  ARM board instead of a much more
                                  powerful, more fully featured and
                                  better supported Xeon board).<br>
                                  <br>
                                  Worse, these variously deficient
                                  devices aren't exactly cheap, either
                                  (well, apart from the Raspberry Pis).
                                  I find the lack of supply of boards
                                  with sensible features quite
                                  thoroughly baffling, especially since
                                  the rock bottom features (if they cut
                                  any more corners they'd be perfect
                                  spheres) don't match the relatively
                                  high prices.<br>
                                  <br>
                                  Instead of leveraging decades of
                                  industry standardization on the basics
                                  such as memory sockets, form factor
                                  (including power supplies), almost
                                  every ARM board manufacturer seems to
                                  be intent on reinventing their own
                                  wheels, and doing a pretty poor job of
                                  it, even though these problems have
                                  been thoroughly solved for decades.<br>
                                  <br>
                                  Not that I think any manufacturers are
                                  listening...<br>
