Actually one of my desktop products received very much praises from the customers who (aside of nice features and responsiveness) also loved how few MB big single exe with no dependencies does so much more and faster than 1.5 GB download from the competitor.

My other current product custom made for a customer in C++ is business server that receives various commands over http, does lots of calculations and delivers data that are used to generate a report (I wrote a report generator in JavaScript and it runs on a browser). The whole thing is again single exe that needs nothing but connection to a database. The exe itself is around 1MB vs again gigabytes for the old mess they were using before and is more than 100 fold more performant. The customer was simply shocked when they saw a result.They did not think it was possible.
