I am wondering how quickly, under normal use, like say 4 hours a day, the iBooks are beginning to look "mucky", and how successful are your cleaning operations?
Why, oh why does Apple have to make this neat little machines white?
Also, do 14" owners - and I am talking screen size here

- fnd the larger screen useful, inspite of the resolution being the same as for the 12" books? My main usage will be to to look at photographic images.
TIA
