Currently own and use a X-T1 for over 3 years and counting.
I haven’t seen any reason to upgrade until now and probably will only buy a new camera if and when my X-T1 will cease to work.
If you buy a X-T 1 don’t buy a new one and buy one lightly used, there must be plenty out there.
You can print huge prints with 16Mp though most people never print anything anyway. Your 5 year old computer will not need any new software to process (I still use Aperture and NIK and LIghtroom 5 and Silkypix 2.0 ) the images and you won’t clog its memory banks with unnecessarily big files that only offer a marginal gain over the 16Mb files.
I don’t film, if I do, HD is more than enough for me, I don’t have any use for 4K and I don’t even own software (or a computer) that could deal with it properly, so, I don’t miss it.
I have taken decent pictures with it but have seen many very much worst pictures shot with X-T2 and X-Pro 2.
I know this is a spiny point of view shared by very few people who look for chops in boxes.
