Hi Robertb,
have you ever experienced the Rocket Ebook (
https://wiki.mobileread.com/wiki/Rocket_eBook )? It weighted 22 ounces and was a "fatty". Yet, in my opinion, it was one of the best designed ebook readers there are- even today. If you look at the picture, you will see that it could be comfortably held with the left or right hand, or even with both...
Maybe you could get a used unit from ebay and check the ergonomics yourself?
Does anybody else think that the ergonomics of the Rocket Ebook were pure genius?
cheers,
kaas
