Hmm... I've just picked up a Nexus 7 tablet myself. I've managed to get Mer partway up on it, hopefully have it usable soon... Anyway, Sailfish should be usable to some extent on this list of devices:

I guess I do feel more comfortable with software I can install onto my own hardware, rather than buying a device with a closed and locked-in OS.
