thanks guys you have been most helpful, but the plot thickens I'm now seeing a new model the T100HA-FU006T which looks to be the 64gb version which has the same Intel® Atom™ x5-Z8500 Processor. i'd much prefer this one as 32gb is going to be gobbled up mostly by windows.
i can get it at a reasonable price but ASUS is confusing the life out of me with all these models, can anyone confirm that the T100HA-FU006T model is pretty much the same as the T100HA vanilla model just that it has 64gb rather than 32gb. sorry to be a pain but want to order that best one and so far from what i can see the T100HA-FU006T is the best deal.
