Nook Teardown
In addition to nook Rooted, nookDevs.com have a Teardown page, with more photos and details of the hardware. The CPU is a Samsung S3C6410 (unspecified clock speed), which is new for dedicated Readers, but the EInk display controller isn't listed.

Based on the BogoMIPS, this is running at 667MHz. The same processor and clock speed as in the SmartQ 5 and 7.

So this would be the fastest processor available on an Eink device, correct? Which makes the nook's slowness all the more anomalous.
Let's hope a firmware update allows users to take full advantage of that speed.

667? I may be dreaming, but I thought the 700 was running on a 1.4 ghZ...?

The PRS-700 and PRS-600 are listed in the E-book Reader Matrix as using a Freescale i.MX31L at 532MHz. This is also an ARM11 core, like the S3C6410, but I don't know which is more powerful per MHz.

Umm... Maybe back in 1995 but it is very fast and very stable now. Hence the reason that a lot of companies are adopting it.

You are generalising.
VMs can be slow - bad software can also be slow. Java isn't the only VM platform out - .NET comes to mind ...
I've seen some very fast Java solutions in my time. A large chunk of mission critical enterprise applications and systems run on JVM, very fast and very stable.

Talk about generalizations. The "large chunk of mission critical enterprise applications and systems" don't run on the Snapdragon CPU tho, they run on multi-CPU multi-core 64bit systems.

Are you really trying to convince me that the well-written code that needs to be translated to the object code in VM is as fast as the actual object code?

Wait, so you slap him for generalizing and then you do it?

Many systems are running JAVA code now and running it well. As a JAVA programmer I can attest to this. Even the military is using it on... wait for it...

MISSION CRITICAL SYSTEMS! I won't even bring up all the sites that are running JSP or servlets to do their business.

Good one guys! I can see both points here. But, I'm afraid this is one of those "how long is a piece of string" arguments. I just have a problem with blanket generalisations and label sticking (aka "oh this is java, slap a "slow" sticker on it").

This argument has been around for donkey years. There is no substitute for good design and good software engineering.
You can cut your code in VI editor using nothing but 1's and 0's, and have it leak memory like a sieve and run like a three legged dog. At the same time I have Java apps running on my Nokia phone which are just fine.

To paraphrase the old NRA motto "Java doesn't make programs slow, programmers do"

Cheers!

PS: Ah, I did dig that "Mission Critical Systems" hole pretty deep didn't I . I think I'll need a ladder to climb out ...
