What I however do know is that: Open-Source software has, more often than not problems perfoming the easiest of tasks with ease.
That's a very subjective statement and opposite to my own experiences. I'm still on a Windows OS but a lot of the software I use is open source (e.g. OpenOffice, Firefox, VLC Media Player, GIMP) and usually, those programs work like a charm. The reason I got into OSS was that commercial programs didn't work the way I wanted (basically, Windows Media Player didn't display videos correctly due to lack of codecs and was unable to give useful error messages). So for the average user I don't really see a reason to fall back on commercial software.
You being a graphics designer, a switch to Linux wouldn't bring you any advantages since in your line of work you need a number of specific programs that don't run on Linux natively (or at all) and for which no OSS equivalent exists. At least, so I assume.
I don't get why you had to have such a trollish OP, though. It's kind of childish.
