Toshiba and HTC had this around 2011 when the mobile OSes were really bad with no updates available, phones produced by HW companies like Toshiba who had no idea on how to support sich HW software-wise. Even the Laptop 3D screen's drivers used to break with the next larger Windows update.
So I'm happy to see these devices return. I hadn't thought that this would happen anytime soon. However, theses are integrated devices again. Bit afraid that the support will be as short-lived as back then.
We haven't kept our FHD 3D TVs for the same absence of updated 3D TVs. But these have unified interfaces at least (Packed HMDI Stereo and SBS or TOB for normal HDMI). So maybe a standard external devices might make more sense than those integrated tablets and laptops.
Time to charge my Fuji Real3D cams once again, I guess.
