We are developing an add on for the Raspberry Pi (tujasdr.com) and I spent some time looking at alternatives particularly because the Rbpi lacks OpenGL 3 support, which would have been nice. There are a lot of boards with stronger hardware which are maybe great for general use, but they very often lack good drivers, for example many support I2S out but very few support I2S in. Also the community support for the Rbpi is great.
