First rule of expensive electronics 101 is don’t get’em wet. For the Japanese, however, a waterproof gadget option’s a welcome value-add to time spent soaking in that ofuro. We first got a sneak peek at DoCoMo’s H2O-resistant LTE Fujitsu tablet just last week, and now the company’s making the announcement official. Joining the Arrows Tab LTE F-01D on the carrier’s new 4G Xi (read: Crossy) network is our good Samsung friend, the Galaxy Tab 10.1 LTE SC-01D. Both slates are set to hit the operator’s Japanese airwaves next month, with Sammy’s bowing in early October and Fujitsu’s model landing a few weeks later. While we’re already privy to all the internal guts and glory of the former tab, we finally have some spec confirmation on the Arrows. The 10.1-incher boasts a WXGA display, dual-core processor running Android 3.2, 1.3 megapixel front-facing / 5 megapixel rear camera setup, up to 32GB of storage and that ever useful waterproofing. Try not to be too jealous, statesiders — there’s always that glimmer of FCC filing hope.
