playbook is an awesome media player.great sound.most other tablets sound teeny.But not recommended for pdfs.epubs..maybe.its heavy.
z30 is recommended over z10.faster; better battery.fmradio.no handicapped stl100 version.But watch out for bad simtray.try and buy.

In all bb10s so far android support is lame.very slow.the jolla phone blows it away handsdown.(future update may change that)
