The most impressive feature that I like about EasyCom was its support for Java programming language as it enabled me easily integrate with my existing business logic written using java platform without any hassle or need to learn new languages such as C++ etc., It provided all-in – one solution approach i.e no separate libraries from vendors were required instead we used only our own APIs hence reduced code maintenance cost drastically; also this helped us reduce time taken by customers while integrating their products into ours because they dont require learning additional technologies rather just learning API's would do! One drawback I found so far has been integration across multiple platforms (web /mobile) - not sure how hard will be but definitely worth exploring given other benefits are big! Have integrated some legacy systems now where majority use windows environment however looking forward towards cross platrorm compatibility if possible too.
