I tried to order one from CPC, but got this:

Hopefully they will ship my B+'s tomorrow.

Compute Module kits show no stock, some arriving soon, lead time 11 weeks :(

All those test points on the bottom of the board look mighty tempting...

Food for thought.
It's the same food for thought that has been regurgitated here many times. It's a pointless idea. Such an SBC would be a total redesign, for which the resources are not available I guess. It would not be totally backward compatible so it's uptake among the two million and growing Pi users would be limited. It would require a whole new OS to be supported. Not to mention all the documentation. It would cause endless confusion among "Pi" users. It would end up just being in competition with the Cubie boards and many others and it would not succeed.
Backwards compatibility, a single "Pi" standard and the longevity of the platform is very valuable to everyone. A whole new design is not, there are already a bunch to choose from if you so wish.
I don't agree with any of your points and/or see any relevance. If there are no resources for a new design then the foundation's is in trouble long term. As it is today, the cubie is not competition. Neither is the Beaglebone due to TI's lame business plan. Frankly I don't see any serious contenders out there today. That could all change... Dropping a good selling item because something bigger and better is out there is stupid. Not even NCR (the second worst managed company I have ever seen) does that.

First of all, Congrats for getting out of beta :) The new revision looks awesome.

Question: Will unpowered HDMI>VGA converters be safer to use with the B+? I gather it was just a matter of 1 diode before...

Yes. The HDMI hotplug supply now has a current limit device on it, similar to the USB output current limit.

Richard, please stop with the concern trolling. You have no knowledge of the Foundations future plans or resources - so you have absolutely no reason to make comment on any long term trouble.

As for resource for development - there is plenty of development going on in various areas. The LCD's are on their way for example. But perhaps it would be useful to understand exactly how long this revision (and yes, it is just a revision) has been in development. I first saw a prototype in January. So in January it had the basic design in place. It has taken 6 MONTHS to go from something that basically works to something that was releasable. And that is a relatively simple REVISION change. Now consider that timescale if it was a new chip, requiring new software (because of course, when released it MUST be at least software equivalent to the current device). I estimate it would takes about 18 months to go from initial ideas to saleable product. A lot of that time is not actually HW/SW development of course- it's EMC testing and the myriad of other things that you have to do to a product to make it manufacturable in large quantities.

The Foundation have a number of full time engineers working full time on all sorts of stuff. Plus interns.

As Eben said, this is the final revision of the Model B. I'll leave you to fill in the gaps.

I look forward to trying out a B+ one day with 2x controllers (SNES style), Wifi Adapter and Wireless Keyboard/Mouse Combo dongle.

Great job guys!

Richard-Tx,
I don't agree with any of your points...
You are of course free to disagree.
...and/or see any relevance.
Well, if you insist on ignoring all the relevant facts then it's easier to disagree:)

I'll leave it to others more knowledgeable of the Foundation's condition, position and strategy to set you straight.

Personally I am very happy to see that the B+ is a very elegant rearrangement, expansion and improvement on the Pi. Whist maintaining 100% backwards compatibility. I would be yawning very hard with total disinterest if they had tossed out yet another different ARM board that needed me to get to grips with and tinker around with yet another Linux installation variant. I've been around that loop so many times already.

I dream of the next Pi being a real shocker, say a 64 bit ARM SoC for starters:) To make the change worthwhile.

No. Would require a big change to the manufacturing process and be too expensive. You can design & build your own Compute Module baseboard if you want :)

Ditto. But of course that's entirely up to the Foundation.
My one gripe is that I've just made a board that puts all the 17 available GPIOs into LEDs. So now I've got to buy a new piece of vero-board, a new connector, a new ribbon, and ten more LEDs (I've got enough resistors) Hmph.
At least 40-pin connectors and ribbon cables (i.e. old IDE cables) are more commonly available than 26-pin variants ;)

Edit: Although looking at http://en.wikipedia.org/wiki/Parallel_ATA I see that pin20 is sometimes used as a key, so you'd need to make sure you had a cable / connectors in which pin20 is connected.

The B+ has a USB port overhang of 2mm (and ethernet is the same).
Great, I know it's a detail but crucial. The current drawing only has measurement to centers no connector widths or heights.
The pedant in me also spots that the DSI connector only has its vertical offset specified and not its horizontal offset. :geek:

May have been just a new product glitch.
The B+ shows on the element14 site as $A38 plus tax, the same as the Model B.
If I'd ordered one last night instead of complaining about the apparent price increase, I'd have had it tomorrow in time for the local hackerspace meeting :cry:

I'm quite lucky w.r.t. those old IDE cables - realised (re-discovered) that I have a dozen or so, most of which are w/o the "pin 20 key", which I'd salvaged from the various PC's I'd put together over the years until it became "just as cheap" to buy one "off the shelf". I also have a few 26-way "crimp-style" headers so I'll probably be making a few 40 to 26 way adapter cables :) .
Trev.

Edit: Having checked the B+'s pinout it looks as if pin 20 is (one of the) a "Gnd" pin, so may possibly be removed to "polarize" the connection?

Just received my first B+ (thank you European Union, merchandize is a breeze nowadays).
The new board is nice and tidy. The status leds are more modest. Just two instead of four. On the old board these light were very bright.
The corners of the board are rounded.

I have not discovered P6, for resetting RPi.
And the socket "Display" underlines a final wish: a special lcd display with touch for the RPi. I will wait patiently.

And remember the 50mA limit through the SoC core. If you want 28 LEDs on it, then max. 2mA per LED, or limit the number on at any one time - or multiplex.

Those are in 2 banks of 14 LEDs paralleled up via one resistor on each side. Not the ideal way to drive LEDs (their brightness varys) but good enough to test.

A reel of about a thousand 270Ω is what I've got, so 270Ω is what I'll use. And no, I'm not going to throw them away just to keep the Pi happy. Maybe I'll put a current limit into the 3v3 line, just to be nice to it, but it'd better be a two-terminal device to replace the bit of wire curently in place.

So the old Pis can use the old floppy ribbons, and now the B+ can use the IDE ribbons from the same source. I still haven't found a use for the SCSI cables. Hmph.

As for the GPIOs 28-31, I'm now confused. I think I need to revisit the spreadsheets to unconfuse myself

Don't be so touchy. You know that my comment re: a 64 bit ARM SoC was made with tongue firmly in cheek. You can tell because I put a smiley at the end just to make it excessively obvious.

I'm certainly not expecting the Foundation to produce such a machine any time soon, if ever. The statement was more a poke at all those who constantly plead for some super-duper 4 core 4 GHz Pi upgrade.
