You made the right decision, and congratulations. I had a 300 when I bought my K3, but I kept the 300 until I upgraded to the 350. I always like to have a reader that is easily used in the Amazon world and another reader that is easily used in the world of ePubs! Sometimes the K3 is my reader of choice for a particular book or situation, and sometimes my 350 is my reader of choice. It is really nice having both options.
