CD is pretty weak, the main manual linked here isn't even on it, just the quick start, which has a few important elements missing that you'd need the other manual for. The quick start linked here has more details than the one on the CD.
At minimum to get going you need power, a serial cable to use flash magic, and an MMC/SD or tftp to store the kernel and rootfs.
A small point, but the front mounted buttons, aren't what i'd call front mounted, they're not even just recessed, you need a pointy stick of about 8mm to reach them through the access holes, which are on the front panel.
The PCB is ok quality a lot of the drill holes are a few mil off and are really close to cutting the track.
It's heavier than I expected. But it so far seems to have a good featureset.
Apparently there are bugs in the supplied uBoot, but the information is not on the CD, it is on the linked PDF though.
The flex cable for the LCD is poorly thought out, straight out of the box mine has a few nicks in the edges.
Olimex stuff is cheap n cheerful.
