The 7" size will be very popular, and that's why Apple is in the process of completing theirs. It's only a matter of time before we see it.
Sooner rather than later is the rumor. I will be ready. My full size iPad in fine at home, but dreadful to take out when I travel. Six months from now... just watch how many of the competitors will have theirs on the market. There is a lot of interest in this size.
Dreadful? Really??? Cue the strings...
