I use a ThinkPad T410 (2010) with i5, 8 GB RAM, and 7200 RPM HDD and a headless Debian server running on an Intel Atom (also circa 2010) with 2 GB RAM and 7200 RPM HDD. Most of my development is done on the headless server using ssh + tmux + vim, though I will use Visual Studio or gvim on the ThinkPad if my current development is targeting Windows.
