Why Linux Sucks
Linux sucks because...
1) No standard package format.
2) User interface keeps changing constantly (Unity, Gnome Shell, KDE 4)
3) Bad user interface design choices.
5) No commercially funded software.
I was told Linux is fast and takes less energy than Windows on laptop, so I decided to give it a try. Biggest mistake ever. Boot time was much longer, nearly every mouse click was followed by UI lag, start menu or w/e takes at least 10 seconds to open, and other problems. Low energy usage? Nope. Linux eats battery faster than Windows while playing medium games (with heavy games it's equal).
What distribution were you using?
And what are the system specs?
Interestingly I've found no particular serious issues with any of those 6 points.
This seems to be a list of "Why Linux is not Windows".
Seriously, if you take the time to do some research, there are a variety of solutions to all those points. If you are too namby-pamby to invest in some time and effort to get the best out of your hardware, then obviously Linux isn't for you, and you can stop whining with basically false information and go back to playing WoW.
