Pico PC's like Zotac's ZBOX lines may be exactly that, tiny, but they aren't completely portable despite their portable size. They are, at the very least, tethered to a power supply to be even useful. One rather intriguing new product, however, tries to address that limitation. This odd GULEEK i8 "Windows 8.1 Smart Google TV Player" indeed comes with almost everything other pico computers have to offer with just a single but very important difference. It has its own 3,000 mAh battery inside.
