Long time ago, I think the early ones had problems so look for a later model, should be info on dpreview etc. I went to a Canon then back to Fuji about 5 years back, the X30, which I still have and love, the EVF and WiFi were the main reason I chose to move to it. I remember the X10 having a lot of fans at the time, I seem to recall having some niggles with the viewfinder but its so long back can’t really recall.
I have an SLR but usually take the X30 cos its more portable. Never been a fan of Phone cameras, likely seems old fashioned to most but I really like to use/handle a proper camera. Quite fancy the OMD EM10 III twin lens bundle £499 at Jessops and sell up my Canon EOS rig so I still have a camera lens options but much one that is much easier to cart around.
