I'm now rocking BOTH an Aura One and a Forma.
I've decided it's a GREAT THING TO HAVE BOTH!
When the battery is low on one, I can sync (or quick check ADE page number for side-loaded epubs) and immediately resume reading on the other device.
Have I mentioned I might, just might, read too much?
I quite love the Forma, and the Dropbox access was very easy to set up and is a feature I'm really liking!
The interesting thing is the arrival of the Forma apparently put my Aura One on notice, as it hasn't done ANY screen weirdness since the Forma arrived. Knock on wood! Love both these readers!
