It has been long rumored that Toshiba will be the first Nvidia Tegra 4 partner, though Toshiba has yet to officially confirm its plans.

Last month, the Toshiba AT-10LE-A showed up for the first time in an AnTuTu benchmark, packing a Tegra 4 processor. Shortly after, the Toshiba AT15 and AT10-A-A-REGZA made appearances at the Wi-Fi Association and Bluetooth SIG.

Now one of the final pieces of the puzzle seems to have arrived, as the first photos of the Toshiba AT10LE-A have surfaced.

The alleged photos come from Greek website, Techblog. According to the site, the AT10LE-A is powered by a 1.8GHz Nvidia Tegra 4 processor, has a 10.1-inch display, microSD, mini-HDMI and can even connect to an external keyboard or dock. The tablet also looks to be running Android 4.2.1 Jelly Bean.

How likely is this rumor? Looking at the pictures and the accompanied brief information, it certainly seems believable enough. That said, it is still just a rumor until Toshiba says otherwise, and should be treated with a healthy amount of skepticism. As for when the tablet could be coming, we have no clue.

What’s really interesting about the Toshiba AT10 is the apparent inclusion of a keyboard accessory. What’s so significant about that? Possibly nothing, but it is at least a little curious that there has been so many rumors lately about devices that potentially work as Android convertibles.

Last month, we reported on a rumor that Intel was working with vendors to create x86-powered Android convertibles. Just a few days ago, a AnTuTu benchmark showed up for a Tegra 4-powered HP SlateBook 10, which may or may not be a convertible device given its “SlateBook” name. Now it looks like Toshiba might be doing the same.

Put it all together, and it’s possible that Android vendors might be looking to further bridge the gap between laptop and tablet by pushing convertible designs.  Of course, Android tablets with keyboard docks have existed for a while now, so maybe I’m making too much of this.

What do you think of the Tohsiba A10LE-A, based on what we know so far?
