Thankfully our local waterstones had a few on display (and working). 350, 650, 300 and one other - makes choosing so much easier.
I was very surprised by the difference between the 350 and the 650; maybe its my imagination, but the 650 seemed to have less contrast?
Regardless of that, both looked good, and I'm so happy that I've got the 350. All my old paperbacks are being shunted up into the loft
Seems to be a lot of interest - we've now got Waterstones, WH Smith and Tesco (the leviathan of UK consumer products) doing eBook stores. Local library is doing an eBook lending service. All good!
