Re: DrXym - how is this better than Cygwin?
"I was not aware of any application development targeted for Linux desktops"
There is a LOT. It is too easy in the windows world to *feel* as if EVERYBODY _ONLY_ does Windows... which is part of the reason why Win-10-nic is what it is.
GTK and Qt applications can be made to run cross-platform, including OS/X. Similarly, Java. DBMSs that aren't SQL Server are often written for Linux FIRST, then adapted to windows later. Similarly, web servers and other server applications. Linux first, then windows [and only if it makes sense].
When you include Android and iOS, UNIX-like operating systems are #1, windows is #2. pun intended.
