so sorry to hear about the death of your eb1150. i've got one (it was my very first dedicated device) and i still love it, despite its flaws. it's definitely the best ergonomy available. i ended up getting a sony 700 to complement it, because i wanted a device with epub support (and a bit lighter so i could actually carry it around with me, which i never did with my eb1150) and because the 700 had many of the features i knew i would miss from the eb1150 (touch screen navigation, highlighting / notetaking function, search...). i love the 700 too but i'm still waiting for an e-ink, epub device that reproduces all the best aspects of the 1150 (the One True Device
).
i'm sure you'll be able to find a new device here which will satisfy your criteria ; don't hesitate to ask questions, we've got a lot of friendly and knowledgeable people around !
