Galaxy Tab 10.1, the benchmark Android tablet device at this moment in time, is coming to the UK on August 4th. Samsung's just made the launch date official, announcing that both WiFi and 3G variants will be hitting "a range" of British stores almost exactly six weeks from now. Alas, no pricing details have been revealed yet, but you can look forward to an exceedingly slim (8.6mm / 0.33-inch) slate sweetened with Honeycomb (3.1) software and dual-core Tegra 2 performance. The 3G variant will also include a 21Mbps-capable HSPA+ radio, which would be called 4G if it were in the hands of overzealous American carriers. The TouchWiz UI will be large and in charge on the British Tab 10.1, augmented with Samsung's Social, Readers, and Music Hubs, as well as access to NVIDIA's Tegra Zone. We're also reminded about the neglected Galaxy Tab 8.9 in the press release, which should be arriving in the UK "later in the year."
