A cautionary BBC tale
BBC's (and Archimedes, for that matter) were the ultimate hacker tool, "back in the day". They came with a documented, powerful OScall interface, and a built-in assembler.
Back in the mists of time, when I was a lowly undergrad fresher, the Physics 1st-year lab had ~50 of these machines - physics labs loved them for their multitudinous i/o ports, and networking. So, being an undergrad, and seeing the floppy-based viruses that were all-the-rage at the time, I wrote a (harmless, just to see if I could) virus that transmitted itself over the network :)
For the tale, and rather unexpected consequences, see http://blog.gornall.net/files/viralConsequences.html :-)
As for Macs - I'm about as hard-core techie-programmer as they come. As a hobby, I learnt verilog, designed my own CPU and implemented it on an FPGA then wrote a C compiler for it; I've contributed to gcc, linux, PHP, perl and more; I've been coding on unix boxes since the time of JANet (shudder), and set up my first webserver when you still had to register a website with CERN. Having established my credentials, let me say that I love the Mac - ever since OSX, that is, it was POS before that. OSX, however, is the best damn unix workstation I have ever used, and I've used a lot.
Still, given the popular (mis?)conception of Mac-users as being all arty types, I grinned at the above.
