FEZ has Arduino-compatible libraries?

Why of course not ... I never said the FEZ had Arduino compatible libraries but it has the same form factor as the Arduino.  ;)

What the FEZ brings to the table is several years of proven hardware development in which I2C, SPI, Serial communications just plain works.  
The Maple is "Arduino compatible" but it seems that Leaflabs have their guru hardware programmer working partime to finish the Maple development project that should have been finished months ago.

Hi Andy

As i have already written i am not using any boards but just testing them for Universities, schools and companies. Sometimes i keep a board to have some fun with it but mostly i give them away to students or friends.
Since the beginning of the year i kept a FEZ Domino Board. Up to now there are still no libs for the use of the Arduino shields, altough this board is Arduino compatible. Everyone is talking about it but i haven't seen any results yet. The Maple and the Coridium boards are only used for decoration and as a cenotaph of how people work.
The last board i've bought for myself was a suggestion of a student. It is the mbed with a mbeduino and a the WDB from Cool Components. You are right you are tight up with the online compiler. But there are a lot of people working to get rid of that. But the best thing is everthing really works. If it is the ethernet, the sd card, the Bluetooth or the USB Host. And even Arduino Boards can be used. It is really amazing. You are not tied to any OS System. You can use MS, Apple or Linux. Tell me about a board that does all this at this price level and i will order one at once.

Scored a (free) LCPXpresso at the ARM developer conference today, for sitting through a presentation on their Eclipse-based development environment.  (actually, it was a good "intro-to-eclipse" talk; one of the better presentations I've been to at shows like this.)

What do you think of LCPXpresso? I am considering getting one.

Well, I haven't used it much yet.  I did get the development environment to work in windows running in VirtualBox on my mac with very little trouble, which I found relatively impressive.

Be careful which one you buy.  The LPC13xx based board I got (for free, remember, so I can't complain much) is relatively "small", even compared to Arduino.  For something larger, be sure you get the LPC17xx based board.  (there is also an even smaller one.)

My initial impression is that if you don't like the fact that "blink" compiles to almost 1K on an Arduino, you'll be really unhappy that the similar sample program that compiles to about 10k in the LPCXpresso environment...  (but that's probably not what you should worry about, given that you can get 128k ARMs for about the same price as 32k AVRs.)

That's weird I thought the ARM processors were supposed to have a reduced code size. Is that because there is additional overhead for setting up the board?

i'm not sure; I haven't investigated yet.  That version did include some debugging code and used some standard libraries that might or might not be efficiently linked.

ARM CM3 claims to have reduced code size compared to ARM ("Thumb" 16 bit instructions vs 32bit instructions), and of course if you need to do 32bit math the ARM will pull out ahead eventually; I don't think I've seen anything claim that code size was small compared to 8bit cpus doing 8bit things...

Maple is great product.
There's numberous competitors.

Netduino,LPC,etc for advance network IC's.Numberous ARM at market.

Thank's

PS:
I'm offering barter or trade

I have read on the ARM website that the M3 has superior code density to the 8/16-bit architectures. http://www.arm.com/products/processors/cortex-m/cortex-m3.php

Has anyone had any experience with the Blueboard? http://shop.ngxtechnologies.com/product_info.php?cPath=21&products_id=65

All the code size comparisons I have made rate the CM3 up to 10% larger than comparable atmega code.

The IDE/compliler suite make a huge difference in final code size.  Most people counter that the CM3 product has 4 times the flash for the same price.

I also have some concerns about a high MHz mpu on a 2 layer PCB.  Noise is very difficult to troubleshoot.

This board sure is good
