I followed this path: (a) Arduino UNO/Mega -> limitations of the 8 bit data. (b) Netduino (Atmel AT91SAM7X512) C# in Microsoft VisualStudio - hopeless speed on interpreted C# and difficulty of adding native code without expensive Kiel tools. (c) Netduino with IAR Embedded workbench - chip programming by USB but no debugging (d) Atmel AT91SAM7x-EK - same processor albeit smaller memory - JTAG connector and a minimal debugging serial port. In-circuit programming and debugging by SEGGER J-Link (I got the SAM-ICE customised version but that might have been limiting for the future) over the JTAG plus printf to the serial port. IAR is free for limited code size and non-commercial use. So far I have found experimentation very pleasant. Be interested to read others comments.
