Mine are IEEE's "Computer" and "Software". Their "Annals of the History of Computing" is also a great read. Horrendously expensive, unfortunately. IEEE also has the IBM journals behind a paywall. I real shame.

ACM's "Communications of the ACM" is also very good.

I can recommend CACM aswell. It's currently my only computer related magazine source. New Scientist magazine used to be worth a look too on a broad spectrum of popular science, it lately became more political and esotheric sadly though.

IEEE Spectrum is their main flagship publication across all interest areas and is one of the best mags still in print.

Also whatever happened to Byte - that was a good read way back when.

Spectrum is so thin however...
