PRS505 v 600
Having both, or rather having HAD both:
JUst being able to pick what you want to read based on environment/mood....
The client software supplied falls over regularly when importing epub books, at around 1500 or so. Lose it and use calibre, you can then more easily categorise documents (books), convert if necessary, and Calibre works with Windows 7 - Sony say their client s/w not supported with Windows 7!!!!.
The contrast of the 505 is far superior to the 600.
The 600 is much more reflective.
The ability to annote documents with the 600 is invaluable. Syncing annotations back is not so much fun.
However, I used both, for a time, on holiday on the beach in Jamaica, and found both eminently useable.
Both take a very long time to scan for books on memory cards. If you plan to keep your entire collection in one place, mm, not on these devices.
Overall... can't live without, and anxiously waiting to get my 600 replaced.
Book publishers - stop being to fekin greedy.
Sell ebooks at £2 each and sell millions...
Sell at £20 each and sell hundreds.
If an omnibus version of say - Harry Potter <spit> - sold for £5, how many copies would be sold compared to the £56 for all that dead wood.
