99 UKP is about as cheap as a new Sony reader has ever been here. The old 5" 350 was more than that, list price.
I tried a Kobo Glo the other day...can't say it impressed me much. My T1 seems easier on the eye.
I don't expect my paper books to have built in lights - I don't expect my e-reader to either. Maybe I'm in a minority on that one.
