Nope, I was shocked by what I saw and I'm not satisfied by the performance of 10536 in terms of speeds so I decide to rollback and got the newer build which is way nicer than the old 10536
However I do have the feeling that I'm using some face-lift wp8.1 only, which I'm not sure what to expect in the future. The features support across different languages/regions are inconsistent. Change region/language/font size require multiple reboot and the 4-column support are not avaliable in all region/language which is crazy. Cortana tied up with region/language is just sucks as hell. Why can't I set my phone in Taiwan/traditional Chinese while keep the cortana working in English/bing search? MSTW is clearly short in manpower and I don't see them capable make traditional Chinese cortana avaliable in any near future. This forced we users in Taiwan either using full English UI to get cortana or just let go this important feature which is very sad fact to be aware of.
