I never had any problems with the X T1. You can use an protection filter on your lens when you want to play it safe.
I always cary a cleaning kit with me. When needed I clean the camera in the hotel badroom. Dry or wet.
Dust, if you are not going to change lens will be a minor problem but a problem nonetheless. A sandstorm is not something that anyone would want to expose his camera to.
There is a possibility to use a Ewa marine protection or even a proper scuba case like the inexpensive Meikon 40 M but it is VERY bulky and not too many lens fit the case. But it is really a good protection and for not too much money.
