I'm listening on the iPad, the Samsung Galaxy Player, and the Clip Zip. I do most of my listening at home so the iPad is the primary device. When I'm doing laundry I use the Galaxy Player (it's attached to a lanyard so I hang it around my neck). I mostly use the Clip Zip for out-and-about or for WMA audiobooks from the library. If I don't buy a Samsung Galaxy phone before year end I'll take
tubemonkey's advice and buy a no-contract phone just for audiobooks. I need something with an OS better than Gingerbread
(On a slightly off-topic note, yesterday I discovered the iPad can do text-to-speech! It doesn't work in all apps but it works in the Pocket app, which is great because I'm forever sticking web articles in there to read later, but
later never seems to get here
Josieb1 mentions an iOS text-to-speech app that can access your ePubs in Marvin. It's pricey but I'm interested.)
