One of the best Ultrabooks of the 2012/2013 phase was the Samsung ATIV Book 9. It got even better with Haswell and a QHD screen in the following version. It’s a stunning bit of kit that I’ll be testing fully over the next week or two.
In the meantime, enjoy this overview video and feel free to ask questions. Price is currently about $1399 for the 128GB/4GB/QHD/Core i5 version. It’s not cheap and one could argue that for that price you shouldn’t have to carry adaptor cables but despite that, the quality, efficiency and style should fit with a lot of customers.
