Accidental leaks are increasingly common nowadays, and one of the latest devices to leak online is the Acer Iconia W3-810, the company's first small-screen Windows tablet.

While Acer was busy boasting a set of large-screen Windows devices, the Acer Iconia W3-810-1600 popped up online as the first small-screen Windows 8 tablet. All Windows 8 tablets so far sported 10-inch or larger displays, but this one reportedly packs an 8.1-inch screen.

According to PCWorld, Amazon accidentally listed the Acer Iconia W3-810 on Friday, May 3, with a $379.99 price tag. The entry disappeared soon after from the retailer's online shelves.

While previous speculation hinted that Acer was busy working on an 8-inch tablet, this is the first real confirmation (although not an official confirmation per se) that the device exists and is ready to hit store shelves soon.

Based on the Amazon listing, the Acer W3-810 will pack a 1.8GHz dual-core Intel Atom Z2760 processor and 2GB of RAM under the hood. The 8.1-inch display, meanwhile, apparently aims to take full advantage of the reduced screen resolution with 1280 x 800 pixels, just like the popular Nexus 7 slate.

Meanwhile, the x86 processor means the slate will run the full-blown version of Windows 8, not the limited Windows RT version. The full-blown version may not be ideal for a smaller screen, but 7-inch tablets are the hot thing right now and Microsoft has to stay competitive.

The tablet will reportedly come with 32GB of internal storage and will have dual cameras, front and back. While Amazon's listing did not mention just when the Acer W3-810 slate will actually hit the market, it did note an unofficial price. The online retailer had the Iconia W3 with a $379.99 price tag. That's more than some Android tablets out there, and also $50 more than the iPad Mini, but it does come with the full Windows experience.

The Acer W3-810 previously leaked on the French website MiniMachines, which posted purported pictures of the yet-to-be-announced tablet. The leaked specs fall in line with what the Amazon listing revealed. MiniMachines mentioned a potential launch in September, so this early Amazon listing in May comes as a bit of a surprise. Until Acer makes it official, however, the Iconia Wr-810 remains in the rumor state.
