Brand new Forum member! It seems that when I am about to decide on which Ultrabook to buy, I hesitate due to reported seriuos issues on the models that I am considering. For instance: Sony Vaio Pro 13: WiFi issues, fan noisy Lenovo Yoga 2 Pro: Wifi and screen color issues with the yellow Samsung ATIV Book 9 Plus: Color issues So, I decided to come to the experts on this forum. Here are the attributes that I am looking for in an Ultrabook in order of importance to me: 1: must be very light - I travel a lot. 2: 13" screen (not 12") 3: WIFI connectivity and reliability must be excellent (ie: hotels, coffee shops, etc.) 4: great screen - I have poor eyesight 5: battery life - not critical because I do most of my heavy work in my hotel room where I can plug in the unit. Lately, I have been looking at the the Sony Flip 13" and the Acer Aspire S7. Your thought and advice would be very helpful and appreciated.
