What makes this anything more than an arduino in a box? http://playground.arduino.cc/Interfacing/Csharp http://playground.arduino.cc/Interfacing/Csharp

Depends on the protocol they use on the USB connection. Serial over USB has its quirks. Using a Leonardo, a Due or a SAMD21 based Arduino allows you to implement something like HID which should give you better latency

  You are right though I do think HID is limited to 64 Kbytes/S. But an SAMD21 or 32U4 could allow me to build a cheaper product. I have to think about it now. What I am currently achieving is - 100Kbytes/S in I2C with a 10Mhz I2C EEPROM and - 2.4 Mbytes/S in SPI with a NOR FLASH at 103Mhz using the FTDI FT4222 and the FT232H should the same or better.

what makes Arduino anything more than an open source Basic Stamp? I was using Basic Stamps a decade before Arduino came along. It's about choice.

  I would think the fact that it is open source as you mentioned is the reason. My question was not meant to criticize just wondering if I missed something that makes these boards a better choice for an application I'm working on. I looked into basic stamp years ago also but the cost of them and my lack of funds at that time forced me to go down the PIC road instead.

You are right in some ways Nusbio and an Arduino with a UART, in term of features may not be that different. With an Arduino specially Chinese Arduino compatible CH340 or with .NET languages you may be limited to 115200 bauds (about 11Kbyte/S) and you need to write and maintain a firmware. As a plus you get PWM and ADC. Nusbio1 can do between 15 and 28 Kbytes/S in SPI and there is no firmware. But there is no PWM. ADC or DAC are available as SPI extensions. it is not a black and white answer. But with the knowledge I acquired creating Nusbio 1 hardware and software, I am now working on Nusbio 2. Nusbio v2 coming sometime this year will address some of these issues, IO default state as input, increase in speed transfer (I2C:Up to 128 Kbyte/S, SPI:Up to 2.4 Mbyte/S), 10 bit ADC, PWM. But unfortunately will be more expensive. see https://twitter.com/MadeInTheUSB/status/848013033335029761 https://twitter.com/MadeInTheUSB/status/848013033335029761
