The ASUS PadFone X due June 6th can be considered as a slightly rugged version of the regular PadFone Infinity flagship line, but it's only limited to AT&T customers. Luckily, for those outside the US, there will soon be a global variant dubbed the PadFone S. These two models are pretty much identical: You get the same 5-inch-phone-to-8.9-inch-tablet transformation, and the guts include the 2.3GHz quad-core Snapdragon 800, 2GB of RAM, full HD displays, microSD slot, 13MP plus 2MP cameras on the phone (1MP front camera on the tablet) and 2,300mAh plus 4,990mAh batteries. The only differences are the 3G and 4G bands for obvious reasons, plus the wireless charging here follows the more popular Qi specifications, as opposed to PMA's. There's no info on pricing yet here at Computex; all we know is that it'll arrive in select markets as early as late Q3 this year.
Also announced alongside the PadFone S are an LTE-enabled ZenFone 5 (A500KL, with a 1.2GHz quad-core Snapdragon 400) and a ZenFone 4 with a slightly newer Intel chip. Both are due some time between late Q3 and early Q4 in select markets. We'll have more info closer to launch.
