Lpc2000

Very interesting in deed,

some thoughts; 
- the 20 MHz might be artificial because I saw presentations from ARM
talking about 100 MHz for the Cortex M3

- the core is VERY new, meaning this is the first implementation in
silicon available, expect some debugging of the core and an Errata
Sheet coming up soon!?

- Once a year has gone, there are going to be more products using this
core with the first problems debugged, so for now, watching it is just
fine, using a proven ARM7 core is our better current option.

- May be the biggest issue, it is not "ARM" compatible, only "Thumb"
compatible. You need to touch any software you wrote for an ARM micro
because this core does not support ARM mode and by definition of all
previous devices any entry in exceptions (interrupts) are in ARM mode. 

Cortex is probably the core to go with in the future, the question
remains when to start using it. Want to be a Guinea pig ;-)
