The Pogo V2 contains a Marvell Kirkwood based on the ARM9 core with no floating-point.
The Raspberry Pi contains a Broadcom BCM2835 based on the ARM1176 core with hardware floating-point.
The Kirkwood is designed for NAS and light server tasks. It has Gb ethernet and SATA ports built in (Pogoplug V4).
The BCM2835 is designed for media playback and games tasks. It has graphics, HDMI out but no ethernet at all.
The Kirkwood is used in a lot of shipping NAS devices.
The BCM2835 is used in the Roku 2.
They're very different beasts.
Madalas naka-sale sa US sites ang Pogoplug V4 (which is the latest Pogoplug, pero almost the same lang siya sa V2 but it has SATA ports)... maraming versions ang Pogoplug, like Dockstar, Seagate Goflex Home, Seagate GoFlex Net, Pogoplug V2, and Pogoplug V4 (Don't get the Pogoplug Mobile dahil walang SATA yun)...
I mainly use it as MJPEG-Streamer devices, just install USB (or SATA hard disk), plug a HD webcam, install Debian and MJPG-Streamer and voila, may security camera setup ka na.... more details in my blog http://rolandsoft.blogspot.ca/2012/12/pogoplug-security-camera.html
