Waiting for my 6400 to arrive! Cant wait! While researching (extensively) before I purchased a flex, I couldn't help but notice that the Flex community seems to be very loyal to Flex and are always very supportive of each other along their journey. Honestly, I think this is half the reason I went with flex because of the excitement around the company and its products. Ive seen alot of blogs where people were ripping on Flex users calling them appliance operators ... blah blah blah... I think they just hate innovation!
