I have not programmed professionally for over ten years. Just out of curiosity I'm wondering if the mainframe still exists, or has the personal computer become all pervading?
I'm sure there are a few out there but I get the feeling that PCs have almost entirely taken over. For that matter does the mini still exist in significant numbers?
If mainframes and minis are still being used in significant numbers then a second question presents itself: do they use GUIs or does the command line/tools environment still dominate?
