I was looking for an Evaluation Board which would be low cost with enough features to test out ARM Cortex M series of Processors. The one which TI provides is a proper development board and cost a lot. So I started my search for an inexpensive and low cost Evaluation Board. To understand the difference between Development and Evaluation Board check the wiki I wrote on Embedded Nirvana.
Comes loaded with 32-bit ARM Cortex-M4F core, 1 MB Flash, 192 KB RAM in an LQFP100 package and cost around $15 (I think excluding taxes & shipping). Not only this, this particular board is capable of being operated on open tools very easily and thus provides a complete packages from being inexpensive, open support and handy peripherals.
The product page has lots of supporting documents to get started and I think if anyone else too looking to get hands on ARM Cortex then this is the board to start with.
