Personaly i will not buy the pocketbook 360, i already owns a cybook i'm quite happy with
I see no point in a second 5" reader.
360 wasn't there at the time I bought the opus, so no question there for me.
Where I to make the choice today i would still go for the opus.
I never was a big fan of the 360 style (taste and colors...). And I woudn't bear ade page number that are anoying enough even with bookeen's trick's to hide them.
And well, bookeen might not be perfect, but no one is, and i know what to expect from them by now.
