As mentioned by Asus a week or two ago, the T100HA indeed is coming. In fact it has arrived! You can pick up this new version of the Transformer Book T100HA for $299 US from the US Asus online store. From what we can see, this is the only place to currently buy it in the US.
If you are familiar with the Android based Transformer Pad from Asus, think of this largely like a Windows version. If you’re interested in a 10-inch Windows tablet that has the ability to become a full fledged laptop computer, this is definitely an affordable option.
With a resolution of 1280 x 800, battery life is a main feature of this 2-in-1. It has 4GB of RAM, 64GB storage (expandable via microSD card reader), along with the Intel Cherry Trail Quad-Core Z8500 processor. There are plenty of ports including USB 2.0, USB Type C Gen 1, micro USB, and micro HDMI. It’s thin and light at 2.28lbs and 0.72-inches thick.
