A tablet is something I would dick around with. Personally, the Iconia, Transformer and Playbook are the most interesting ones at the moment. I have an iPhone, an iPad 2 has no "new" or interesting features to me.
Cost wise, Iconia is the one I'd consider, but the playbook is exceptionally unique as well and more geared towards what I'd use it for.
Or, I could wait to see if Lenovo's $199 tablet is worth considering (end of September supposedly)
