Well, my Oasis arrived today (from Amazon.de). It has all the faults mentioned here on MR in various threads (uneven frontlight, scallops, lesser contrast and yellower screen than the Voyage), but I'll keep it. The uneven light and scallops are not visible in my normal reading conditions (I never read in the dark or very dim room), so they don't bother me. Besides, my Voyage's frontlight is actually more uneven than the Oasis's. The lesser contrast is noticeable when viewed side-by-side with the Voyage, otherwise it's good enough for me. Certainly it's not so bad as to be a dealbreaker. I really like the shape, it's the first Kindle I feel comfortable reading without the cover.
All in all, the Voyage has better screen, but the Oasis has better shape. I'm going to use both of them.
