I just picked up a Nook HD this past month, and with the addition of Google Play, I'm very happy with it. I've never been wedded to a single font, so that's not an issue at all for me. I've now got a handy ereader and tablet that I can carry around easily and which takes care of all the quick look-ups I tend to do during the course of a day, and which is easier to read than the same info on my cell phone.
I'm not worried about B&N going under because I strip the DRM from all my purchased ebooks so I'm not dependent on them being available from B&N's site. As long as the device continues to work, I'm good.
