I just pulled the trigger in a z20t-B Happy to be here strange turn of events. I just sold my Fujitsu Q775 because of some issues with the elan trackpad that I couldn't overcome. Stumbled upon a z20t-B for a great price 5y71, 8gb, 256gb SSD and here i am I been lugging around a 4.6 lb Q775 for a while. A 3.2 lb z20T will be amazing to me! Does anyone know what is the smallest wattage power supply i can get for a core M processor machinese such as the z20t?
