No NeXTstepper. Spectrum, then DOS/Windows (Basic, Pascal, C, C++, Python), then Linux (C, TCL) and now iPhone (Obj-c).
Since I started with TurboC, when I jumped to Linux I found RHIDE and later Setedit (
http://setedit.sourceforge.net/), but it had lots of character display problems with the different terminal emulations and such, so I learnt vim because it was more suited to hacking over a slow dialup link.
Python could be considered my first love, but the thoroughly poor Snow Leopard interpreter implementation forced me to look into Pyrex, Cython and other ways to come around the poor performance. Years ago I disliked C# and while I don't like the language much, the platform seems to be growing interesting stuff with Mono, Boo, and of course, Cobra, among others, which is the reason I'm lurking here.
