I'm still missing a normal round power plug, as the ramshackly micro USB draws much more power then the allowed 500mA. Also Ethernet is still connected via USB, and horrible slow.

The Ethernet chip is a new one tho - maybe it's a little less terrible? (No idea - my applications for the rpi don't depend on it being a speed demon on the network.)

the ethernet chip seems to just be the 4 usb-port version instead of the 2 usb-port version.

Have they fixed the stability issues when it is under high load with a lot of networking traffic? I have a RaspberryPi B and each time I start a large file transfer the entire board locks up. Doesn't matter what version OS I am running either!

Have you tried another power supply? I used a "high quality" one from RS (I think) and had odd problems with disk corruption and crashes when pushing the limits. I switched to a old iPad charger and the crashing problems went away.

What's the same: - Same Broadcom BCM2835 Chipset - Same 512MB RAM - Same full size HDMI port - Same 10/100 Ethernet port - Same CSI camera port and DSI display ports - Same micro USB power supply connection What has changed: - Now comes with 4 USB ports so you can now connect more devices than ever to your Raspberry Pi. - There is a 40pin extended GPIO so you can build even bigger and better projects than ever before…

The whole point is that most people (especially the target market) have a spare USB charger hanging around. The Pi takes exactly the same connector as your mobile phone - it's one less bit of kit to buy.

"Fantastic" may be overstating it. I've been running Raspbmc for about 15 months now, and although the video rendering is very good, the XMBC UI is a bit laggy and unresponsive (although there seems to have been an improvement recently). I've also used it as an SFTP client and to run a few light cron jobs (rock solid there). Given the price, I am pleased with it, but I wouldn't recommend it as a media center for the…

Agreed. I wish that RPi has some kind of cheap prebuild of a mediaplayer. If would be GREAT for non-techies if it just had a real power on/off switch, IR sensor & a basic remote that just works (probably asking for too much there). I reckon you could fix the lag of the GUI if someone implemented Raspbmc/OpenELEC with Wayland instead of X-server. Not much has to change for this to be possible. Only the power switch &…

It seems Wayland support for XBMC was merged last October[1]. Not sure if it will benefit on RPI.

The Ethernet speeds are limited by both the USB bus it's riding on, as well as the slow CPU processing power.

Although, for most of my projects so far, it's been plenty fast.

This is quite the impressive release. The additional USB ports are a welcome addition, as-is the additional GPIO. I have one project in particular that will benefit from the additional GPIO.

The microSD slot is also a big deal. microSD's are much more common now-days than SD's due to most people's phones having them. I own a slew of old mSD's from old phones and can re-purpose them into a Pi project now :)

Ebon Upton [0], one of the main folk from the Raspberry Pi foundation works for Broadcom and does SoC. So odds are slim considering that connection probably enabled them to get extreme price arrangements otherwise not doable. [0] http://en.m.wikipedia.org/wiki/Raspberry_Pi_Foundation

His Broadcom relationship is probably much less relevant now that the foundation has some money in the bank and a product that has achieved wide spread success.

Exactly, there shouldn't be any trouble getting a vendors attention now.

This isn't a good idea though I've heard, don't you bypass some important components for power safety in the micro USB power circuit?

You're bypassing a fuse. If you have a crappy powered hub that isn't well regulated you could fry your pi. In reality, the chance of that happening is very small, and safety here is only in the context of the "safety" of a $35 board. Most hubs won't let you draw more than a couple of amps anyway.

Well, I'm not sure how well regulated my $3 powered usb hub is. I find myself having to do this weird ritual of plugging stuff in under the correct sequence otherwise I get some power from the hub and the pi won't boot fully (goes into a weird boot loop).

Agreed. Big win on the microSD. They are also becoming very affordable, especially < 32GB

Curious they're explicitly naming this the "final evolution". First up, I'd be surprised if they continued with a "Raspberry Pi 2" soon. The RPi is still very adequate for its original goals in education and will likely remain so; it hasn't ever been quite enough for people wanting a cheap server or media center except for those with very modest needs. Given their announced goals, I doubt that the creators are going…

I think that the fuller quote "the final evolution of the original Raspberry Pi" is important. The word "original" in there doesn't lead me to believe they are at the end of the road overall, just end of the road for this one design.

To clarify, I expect to see a more complete redesign in the not-too-distant future. If nothing else, you want to use components that are recent so you can keep producing more of them without increased costs for legacy components.
