What is the difference between a "Dev Board" and an "Evaluation Kit"

Some subtlety is being lost on me here.

About £100

Think of a Dev Board as a home built PC which makes an Evaluation Kit an overpriced Named brand PC, not naming names, um Apple / Dell.

Evaluation kits usually come with extras like ICSP, IDE's and such, where as Dev Boards are usually DIY.

Thats my experience anyway

IMHO:

Evaluation Board: Non-programmable "demo board" you can use to poke and prod a device you are evaluating

Development Kit: Evaluation Board + ability to program devices and develop new code over serial/JTAG interfaces (or similar), can function as a development platform until custom hardware is developed.

The Flexible MIDI Shield: MIDI IN/OUT, stacking headers, your choice of I/O pins

IMNHSO, a Great answer too.
