We'll probably never match Japan's obsession with waterproof gadgets, but anyone would appreciate how the local manufacturers also manage to keep them thin and light at the same time. The Fujitsu Arrows Tab LTE F-01D we fiddled with here at CEATEC is one such example: while it's thicker than Samsung's 10.1-inch counterpart by almost 3mm, we were surprised that Fujitsu's latest Android tablet also weighs just under 600g -- not bad considering it's suitable for use in the shower.
