Hardened... Not really... But I can't recall anything recently or in past for that matter so easily smacked off. Just a little light flash.
I mean, it's a little bizarre but not anything I'd really worry all that much about. For most it won't be an issue, not all flashes do it (The flash on my Galaxy S3 is LED based) and it doesn't kill the Pi... just causes an inconvenience of having it stop/restart.
Well, this little flash creates a high powered electromagnetic impulse very close to the electronics. And it seems this chip is very susceptible to electromagnetic interference. This could be avoided by shielding or something else, but is probably not necessary for the raspberry Pi.
I am sure a lot of the electronics you use every day also don't like heavy electromagnetic interference, but they usually have cases and other shielding to protect them.

All that's going through my head is "moar power!!!" and like... I don't know... pictures of monster trucks and explosions.
This is gonna be sweet!!!

Speaking of MOAR POWER, I've been eyeing this bad boy lately. $100 includes the board, case, power supply, micro HDMI cable, board cooling fan. All you need is an SD or eMMC card and you're good to go!

If the link is b0rked, search for ODROID XU3 Lite

The RPi2 behaviour is not uncommon at all. If you go around any live, unshielded consumer board with a EMC immunity tester, malfunctions or faults are the norm. I know first hand because, when I worked as electronic engineer, I sometimes had fun torturing random portable electronics on the EMC bench, while my coworker (the one that spent all day testing our own industrial products) said witty words about the "weak", cheap imported consumer products and their lack of EMC practices. I put 6-7 discrete components just to stop the interference on some microcontroller inputs. On a consumer board, there is nothing like that.
If you want to see funny things, go aroud any portable digital electronics with a piezo igniter or anything that does make strong electrical sparks. Be aware that this may damage the weaker products.
This is the reason why any serious safety/industrial/military board is conformally coated, shielded and usually has a 6-layer PCB with ground planes on the exterior layers. The rasperry pi foundation blog took this opportunity to explain the photoelectric effect. This is the same effect experienced on some glass encased components. If you are concerned with this, just put the RPI in a black case. Problem solved.
Was a joke. I'm not even sure if I have film laying around somewhere for that thing. Haven't touched it in ages.
On the other hand would be funny to see how this thingy reacts during a lightning storm.

I've got the ODROID-C1. While development on the board isn't as fast as the RPi Community, it's a fast little board and it does everything my RPi1B couldn't keep up with. I'm eyeing the XU3-lite as a desktop replacement given that my current PC is a first gen P4 (no HT) 640MB RAM, 320GB (spread across 4 IDE disks) mid-tower.
Loud, power hungry, and probably no longer upgradeable = Time for a new box.
Haha wow. I didn't know P4s were still used as desktops! Props to you man! I ditched my old AMD Athlon 64 desktop like 6 years ago. The ODROIDs are awesome I will admit, but they don't have the enormous backing of the Raspberry Pi community. That's mostly what's keeping me from purchasing an ODROID. Definitely worth a look though. Definitely.I've got the ODROID-C1.

MicroSD arrived today!

Ordered mine yesterday looking forward to install plex wonder if it can handle it.
Well... botched the network config on the Pi when trying to setup this... http://hackhappy.org/uncategorized/how-to-use-a-raspberry-pi-to-create-a-wireless-to-wired-network-bridge/
I'm not a smart man.
Anyhow, starting fresh and doing a reinstall. :O

How about some quick RPI porn for ya? Got a case and new WiFi adapter today... Case is really good quality, I like it! I'm going to mount this on my wall with some other stuff eventually so I like how it has the mount holes already.
I actually bought some cheap heatsinks that will come in tomorrow, I think, so that'll be the final addition as far as accessories go.
I almost bougtht a PiGlow (shown below) for random tinkering. The LEDs are controllable and can be used to visually display different information based on brightness, color or speed but decided against it for the time being. Maybe in the future though!
