I'm still on the fence, since the 300 has now come down to $349 (BB).
I was totally sold on the 700T, but since I bought a 300 for my daughter and have played around with it, now I'm not sure.
But your post has me leaning back towards the 700T. I'll buy one or the other in the next few weeks. If I buy the 700, it will be the champagne. 300 will be the blue.
In either case, I now doubt that I will buy the keyboard. I really don't think I will use it that much.
