I'll skip this model and keep hoping for another announcement in the not too distant future.
I love my Forma and I've been considering getting a spare but I've been waiting to see if there'll be a refreshed version, although the only real improvement I think it needs is a less sludgy power button. My hands are not strong but even though the Forma is large it's amazingly light, and the soft non-slip surface and the front-tilted wedge make it easy for me to hold onto. I might die if anything happened to it, so I suppose I should go ahead and order a spare anyway in case whatever new model comes along is less desirable and the current model becomes unavailable.
If they made a 6 or 7 inch version of the Forma I'd get one of those too; I like my Libra but it feels heavy to me and it's too slippery to hold without a case so that makes it even heavier. A smaller Forma would feel almost laughably weightless and the size would make it more portable.
Kobo could have gotten me to order a Nia too though, if they'd made the whole thing (front and back) yellow or blue like the covers or, even better, a red metal-flake finish like my Sony PRS 650.
