Yes, I only use AdobeViewer. I've thought about looking at CoolReader but never quite summoned up the energy - I couldn't take the disappointment if it still doesn't support CSS properly

After the last year's fiasco with PocketBook continually failing to deliver a fully working v15.3 firmware I'm rather disillusioned with PB as a whole. It's a nice little reader but it could have been so much better, if only everything just worked as it's supposed to.
I do most of my reading on my Sony PRS650 these days. I just use the PB360 when I'm out and about.
