If you have not cancelled, I would suggest you take another look. I have a tablet, android phone and laptop and the Pandora leaves them all in the dust.
I might take my laptop with me while I travel but it is the Pandora that I use the most. I take my phone with me, but aside from reading ebooks and making calls, my Pandora is what I use. And I use my Tablet for presentations and speaking, but my Pandora is what I do most of my work and entertainment on.
Hang in there. You will not be disappointed.
Just my view...
