After about 2 years and try 3 different distribution of Linux (Ubuntu , Fedora , open Suse) finally i migrate completely into Linux operating system.
I am very happy now because i think i use my hardware efficiently compare to past that i was on Windows. At last i select Ubuntu from different Linux distribution.
Almost all my software need are exist in Ubuntu (Office , IDE , Web Browser , Media Player , ...) but my major problem in this migration was (already is) hardware driver , some of my hardware device installed hardly (very hard) and some other did not install yet or did not work in good performance (e.g. WIFI).
But in overall i am glad , Linux world is very nice , stable and fast (compare to Windows).
have a nice time.
