Raspberry Pi 2 Model B
The Raspberry Pi 2 is a small single-board ARM computer. It has a 900MHz quad-core Broadcom BCM2836 ARM7 SoC and 1GB of RAM.
It's not a bad board, but I think it's been way over-hyped. The hardware is not very fast (compared to other ARM boards at the same price point) and requires binary blobs to work.
I was disappointed that the expansion connector doesn't have the pins labelled on the board's silkscreen (or at least color-coded). For a board that's supposedly targeted at educational markets, this (along with the closedness of the hardware) is a serious issue.
