I've used a few different distros of Linux starting with Red Hat Server 7 (In school) and Mandrake 9. I've always been interested in Linux, and wanted to know what the hype was all about.
I never really got into Linux until about 3yrs ago when my hard drive died, and I had to borrow one from a friend, and he brought over that and a copy of Mandrake 9. He ended up bringing over 2 Hard Drives which I thought was rather odd at the time. Later I found out that one was for the Linux Swap! And thats what really got me started. I had to use linux for about a month while I waited for a new hard drive.
I used Linux off and on. Going from Red Hat, to Mandrake, to Lindows (or Linspire), then the most recient one that I used was SuSE for a while while I made some security changes to the network, and while my laptop was in the shop. All the while, my brothers complained.
I've reciently become fedup with Windows and wanted to use just Linux. I tried to install Mandrake 9.1, and then Red Hat 9 in VMWare, but for whatever reason, they both failed. I ended up downloading Mandrake 10, but it didn't want to run properly in VMWare. So I tried SuSE 9.1 and since that failed in VMWare (I think my windows was fux0r3d at this point) that I just formatted the drive, and installed a dual-boot of SuSE 9.1 and Windows XP.
I've been learning a lot, and use SuSE 9.1 as my primary OS. I go back to Windows now and then if I need something from a drive, that I can't write to in Linux. I've now learned how to manually mount a USB Hard Drive, and how to install an RPM. What I need to learn now, is where to find (and install) the make command so that I can compile an installer for some programs that I download.
I can watch movies, and download torrents and burn them, I can copy discs all with Linux!
I find that Linux is customizable, and its also very fast! Well, compared to Windows anyway. Booting into Linux takes half the time, and its also more secure!
I did a test, where I loaded a few pr0n sites that I knew had a lot of Spyware and adware on them. Linux came back clean, but when visiting them with Windows (as we all know) became infested with them, and a virus! So, for security I deffinetly prefer Linux.
I'm going to be making the final switch to 100% linux soon. I just need to convert my external 160GB Hard Drive to FAT32 so that I can write to it in Linux, and then my transformation will be complete. I have VMWare for Linux installed, and if I ever need Windows for something (to test a Windows program) then I'll just use the virtual machine! But other than that, I will rarely use Windows (unless I'm at work, or fixing a computer). Linux is the best choice that I have made!
EDIT: WOW! I just wrote a small book!

EDIT2: There we go. made it all nice and readable... well, more readable than before
