nexus 7, and 32gb if you can get one for the right price. it does all that you list and can easily stream media to other devices on your wireless network making the lack of hdmi somewhat moot. Only downside is the speaker is nowhere near as good as the pb. id get a cheap cover sleeve for it, too, as it does not feel as sturdy as the pb (that said, both have taken small falls and the pb gained a small chip in the edge while the n7 did not!).
another downside may be that it'll show you how much better android apps work on android devices, putting the pb runtime to shame
