On my normal workstation (intel based linux machine) I use PWM as an window manager. Great to use, very minimal and very fast. And it has the one thing that I really require in a windowmanager, and that is sloppy focus. That brings me to point #1 why Mac OS X sucks - No Sloppy Focus
Another point that is very annoying in Mac OS X (according to myself ofcourse), is the fact that the title bars and menu bars are using quite large fonts. I like them small so I can cram more on my display (which is needed with the relative low resolutions that the iBook and Powerbook have).
Another thing I miss in Mac OS X is that there is no default package management system, ofcourse you could install fink or darwinports, but still it stinks.
A little related to the above point is the fact that there is no default development tools installed, you have to download this enormous package yourself. No way to download individual tools, no you got to get them alltoghetter. Which is a pain in the ass if your normal OS is Debian.
Also there is no 'advanced' mode tot configure things in the GUI, these have to be done in the old fashioned text style way. The problem with this is that these changes are going to clash with changes made GUI wise.
Why Mac OS X Sucks in 5 points
- No Sloppy Focus
- System fonts way to large
- No Default Package Management
- Development Tools not included by default
- GUI tools do not understand manual changes.
