Suggest wait for 550. Windows 10 is nice and much better than windows 8.1Yes I'm sure that you can upgrade 535 later to windows 10 (I upgraded my 532 to windows 10) but on it's current status I'm having few issues like battery not charging properly. Others reported that wifi not connecting (not sure which models though).
However, battery life with same casual usage in my experience is better with windows 10 compared to windows 8.1 so I'm sure will re-upgrade again to windows 10 when it goes live.
However I may buy 550 later though as that device is build specifically for windows 10.
