what caused you to get into Linux?

Curiosity. I was a curious tweenager, and I was already a bit of a geek at the time. I read about Linux in computer magazines at the time, and decided to give one of the free CDs a try - with RedHat 5.2 on it. To be honest, wasn't really impressed with it. I especially disliked having to recompile the kernel, which took ages on those Pentium 3s. But it got me exploring other operating systems, and I found QNX, BeOS and NetBSD. I was really impressed with with QNX and BeOS in particular - Linux felt quite clunky and amateurish in comparison. I especially liked the multimedia performance of BeOS, and the lightweightedness, polish and desktop responsiveness of QNX, which featured a real-time microkernel. QNX felt lightyears ahead of it's competition at the time. My first run into it was a free 1.44MB demo floppy that the company mailed me directly, complete with a full developer manual (which was completely wasted on me as a tween, but I still appreciated it and tried to comprehend bits and pieces). I was already into making custom bootable floppy disks at the time, so I was extremely impressed that they managed to fit in a full fledged GUI desktop, complete with a browser that supported Javascript (along with network drivers and a modem dialer) - all on a 1.44MB floppy disk! Till date I've no idea how they managed that. Even the tiniest of Linux WMs are massive in comparison and look fugly (twm), but QNX's Photon microGUI somehow managed to make it good looking and functional. Maybe it was all coded in Assembly, I don't know, but it was, and still remains, very impressive nonetheless.

I digress, but all this started getting me into exploring POSIX systems and distro/OS hopping. It was only when I experienced SuSE that I fell in love with Linux. Finally, I had a polished Linux desktop, with a full-featured settings/control panel (YaST) that made it easy to use even for a tween like me. And that's when I switched to Linux as my main-ish OS, with Windows relegated to gaming duties. However, I didn't fully get rid of Windows until Windows 7. I was actually impressed with the Windows 7 beta releases and was prepared to buy it at release, but... I wasn't expecting that price tag. I was hoping I'd get a student discount, but it wasn't applicable where I lived (or there was some catch, I don't remember exactly). In any case, I couldn't afford it, and I was really disappointed and angry at Microsoft that they were charging so much for it here, compared to the US pricing. And so, on the release day of Windows 7, I formatted my drive and switched to Linux full time, and never looked back.
