The eBay deal, via GeekDeal, is $140 off the standard price for the Nexus 10 tablet, which can run Android 4.3, the latest public version (though it may require an OTA update upon opening the box). This is a 32GB WiFi only model (honestly, though, Google never released a cellular-based version of the device).
The Play Store's price is $499, so this is a cut of about 28 percent.
In addition, sales tax is only charged by the seller in the state of Washington, meaning genuine sales tax savings for the other states.
Although the Nexus 10 -- built by Samsung for Google -- has some nice specs, with a 2,560 x 1,600 screen, its System-on-a-Chip (SOC) processor and graphics processor are somewhat dated. The device has a Exynos 5 Dual CPU, which is a dual-core ARM Cortex-A15 processor and pales in comparison to the current SOCs shipped in tablets or even smartphones. Its GPU is a Mali-T604, similarly dated.
The Nexus 10 joined its smaller brother, the Nexus 7 last year, when Google expanded its Nexus line of products to tablets. The Nexus 7 line was eventually expanded to include cellular versions, but not so, the Nexus 10. Nexus devices are sold with stock Android and with no UI layer or OEM additions, but just pure Android.
We expect, since Google recently upgraded the Nexus 7 to a 2013 model, that Google will soon release a Nexus 10 upgrade. We'd also expect that Google -- or rather Samsung, the actual manufacturer of the device -- would not opt for a higher resolution, but we would expect to see significant changes in terms of performance, with a better processor. Last year's model sported 2GB of RAM, so we aren't expecting a bump there, either.
We always warn about the safety of buying such a device on eBay, but GeekDeal's feedback offers a sort of guarantee. The eBay seller has about 165,000 feedback reviews, with an overall 98.9 satisfaction rating. Honestly, while with that many transactions, there is virtually no way for a company to maintain a 100 percent satisfaction rating, we prefer to see satisfaction ratings over 99 percent. Still, at this price, it's hard to avoid clicking on the Buy button.
The sale says that there is a limited quantity of devices sold, with only 29 purchased so far.
