Why?
My studies at school will still need Windows environment.
Then Why linux-only?
Windows is so insecure. I'm gonna format the whole thing in ext-4 and put Linux on. Recently,.. two two laptops belonged to two of my friends were lost with their important and confidential data on hard drives. They both were using Windows. Windows filesystem and password encryption algorithms provide almost no security compared to Fedora. Soon,... as I find a temporary place to back up my data which is about 100 gigabytes,.. I will completely turn my hard drive into an encrypted ext-4 system. Simple, free, open, but secure. :)
Even if my laptop is stolen, nobody will be able to find out what I was up to, unless the thief is also a professional cracker.
What's next?
I need to borrow a portable hard drive, to back up my data. Unless I use a portable hard drive, it may be costly to back up all the things into DVDs. Then reformat my hard drive,... install Fedora 11... the upcoming OS on the newly created encrypted drive. Sometimes I may install Ubuntu aside. Finally get my data back and shred the backed up data to prevent unexpected privacy circumstances. :P Additionally I may set up Virtualbox to install Windows XP on a virtual partition.
Several people in our junior batch have become completely FOSS dudes,... so why can't I? Actually, for people who do Computer Science it is easy to switch to Linux,.. but for ICT people it could be bit hard.
Wish me good luck!
