Since I get a new phone every 2 years I could wait a couple of months for better, newer hardware though. SD800 devices are said to use Quick Charge 2.0 and Voice activation, which are ONLY available only for the SD800 devices. I read somewhere that there are already 55 SD800 devices in the works (source
), so waiting a couple more months for a significant performance boost, even lower battery drain, and charging the battery up to 75% faster seems logical to me. (Not to mention encode/decode of 4K HD content, 50% boost in graphics and 100% boost in performance due to Adreno 330, 50% faster LTE bandwidth and clocked to 2,3GHz) Those are a lot of high percentages! Voice activation could be interesting, but I rarely use voice so that's not a big deal for me. Maybe in the future when Google Now becomes available in the Netherlands though.
The comments are understandable that you should not wait for the next best thing as you will end up having nothing. But a few more months for such a performance and feature boost, to me, is a better insurance my phone will keep up the next 2 years (hardware wise).
But thanks again for the replies!
