They've upgraded these since the T100TA, they now boast up to 12 hours battery life, the new Type C USB 3.0 Connector, and a faster Cherry Trail Quad Core Intel Atom Z8500 CPU up to 2.24GHz and the associated increase in performance to the integrated graphics.
Unfortunately it is still somewhat crippled by only 2GB RAM (soldered), and a very meh screen but its fine for general use.
These used to be a bargain at $450 https://www.ozbargain.com.au/node/130839.
For $342 for the upgraded model seem like a pretty stellar deal.
Today only so get it while you can.
Remember to take advantage of Harvey Normans $25 newsletter signup offer and see if officeworks stocks the same model to get a price match.
