I was sorry that I didn't wait a couple days, as I just bought my kids two Viewsonic 7e Android tabs (running Gingerbread) for Christmas, for them to use at university. Could have got them Playbooks for the same $199.
Then my son showed me his active animated background (the planet Vulcan). And my daughter asked me which of the six or seven office packages available in Android Market she should download.
I guess on the plus side, they have to buy sdhc cards to bump up the memory from 4GB to my 32GB (well, they'll have 36). Is that a plus for the PB? Suddenly my full price 32GB Playbook seems ..... inadequate. As does the wife's 16GB.
