I was going past the shop that I found the one sole display version of any ereader whatsover and was able to find a shop assistant who was atually able to get it working again. It was a kindle paperwhite and while I loved the quality of the e-ink I definitely prefer the ergonomics of my old kindle with the turn page buttons on both sides. If I could put the sreen of the paperwhite with the hardware and software of the kobo onto my 4th gen kindle I might just have the perfect ereader!
Failing that, it looks like it will have to be the Libra H2O!
