Luckily I heard about the curved Dell U3415W before I bought the AOC 21:9 because the Dell is only 150CHF more. 889CHF in total. The other curved LGs are starting at 1200CHF+ so I think the Dell is a pretty good deal. Especially with the better stand, HDMI 2.0 etc. Today my retailer in Switzerland listed it and I ordered it right away. But no delivery date yet. Hopefully that changes in the coming days. Going to replace my U2711.
A review by Linus would still be nice though ;-).
