Thanks - I have the Kindle DX, but it's slowness and general lack of flexibility is a significant negative that doesn't really balance out its superior page experience compared to a tablet. This is much more of a thing with tech manuals where reading is far less sequential than fiction or articles.

I'm aware of the new breed of large readers but haven't been able to try any, and I'm concerned they won't be powerful or sturdy enough compared to the fragile, sloooow DX to justify the outlay. I don't have much use for notes.

I realise the DX is a dinosaur though compared to the new ones you are talking about, and would love to be pleasantly surprised by a quantum leap...
