I came here to pretty much write the same comment. I also had my first Linux experiences via Ubuntu's CDs via post scheme. I grew up on a farm with poor network connectivity, so for a few releases in a row, I would apply to have them sent. I started using Linux at about 14 years old. By the time I was 17, I'd been offered an undergrad level job at an award winning software development agency. I don't think that would've happened if I hadn't become very interested in Linux at such a formative moment in my life.
Before I managed to get WiFi working (I had lots of trial and error with ndiswrapper), my very first triumph was getting a USB-powered "winmodem" to work with Damn Small Linux (which I got for free in a magazine). One of the websites I used seems to still be online: http://www.linmodems.org
While I am so thankful that compatibility and ease of use has dramatically improved since those heady days, I honestly think I wouldn't have gotten the career I have without that struggle and the curiosity FOSS provided that drove me to push through and learn something.
