According to Microsoft OEM pricing information -- a screen capture of which is embedded above in this post -- Windows 8.1 with Bing is listed at $10 per copy for "small" Intel-based tablets under nine inches in screen size. But after a "configuration discount," of $10, OEMs get that SKU for those tablets for free. For tablets with screen sizes of smaller (not greater, as I originally mistyped) than or equal to 10.1 inches, the Windows 8.1 with Bing SKU is listed at $25 per copy, with the same $10 "configuration discount," resulting in a $15 per copy cost for OEMs.
