Linux sucks

I'm copying 200 GB to Truecrypt partition and it freezes system every two minutes. Who wrote IO? Some moron, apperantly.

Everything in Linux sucks. For example, when I close "Nautilus" file manager window, it doesnt terminate program, but puts it in background. Why? To leak more CPU and memory!
The xfce4-menu-plug already ate 140 megabytes of memory, and it's just a toolbar! When I try to `kill -S gnome-screensaver`, it blanks whole screen and only reboot helps. Gedit (a simple notepad) takes whooping 60 megabytes to edit a few lines of text and it loads about 10 seconds! Opening a directory in files browser sometimes takes minutes, due to its file type detection feature (it scans and makes thumbnail of every file). Thousands of thumbnails stored inside ~/.thumbnails slow down image viewer startup by about 20 seconds. Invoking `cat` on a binary file damages terminal output and sometimes crashes bash.
