It seems to be really tiny & cheap.
2Ghz over-clock with a heat sink?

The heat sink is Huge!
This toy is really appealing to play with but not for further development of any system. Same as with R-Pi. Samsung will make another CPU for smartphones in 6 months and this one will be obsolete
Im surprised with this
The heatsink also serves as an enclosure.
The CPU module of the ODROID-X which it's based on gets quite hot and powers down with large compiles such as building a kernel with "make -j 4". A 2" x 2" fan placed above it makes it run cool.
Still quite useful and a good price, think of a quad-core Pandaboard that runs at 1.6GHz.
Time taken to build Ubuntu linux-image and linux-header deb packages and uImage is impressive with no need to cross compile.
I use a 32GB full size Class 10 SD card - microSD cards in an adaptor do not work as the adaptor distorts the signals.
I have added a 60GB USB IDE HD and also nfs mounted a HD from my main x86_64 box with 512GB spare.
