I've used DOS 6.22 and 3.1 - did the job, slowly.
95 - ditto, quicker.
98 - slightly better.
2000 - I liked it.
XP - a bit flashy, but OK.
Vista - mmm. Brief acquaintance (long story I'm not going to tell). I admit to liking the Aero interface - my laptop never had speed issues.
8.1 - loved it.
10 - don't like it at all.
11 - like it about the same, i.e. not at all.
I've also used a BBC Micro, a TeleType (stop laughing, this was 1982!), plus SUN Workstation, UNIX and VAX/VMS terminals, programming in UNIX, various BASIC dialects, C (a joy - using Jackson Structured Programming tends to reduce a program design to the ideal of all being functions), COBOL (a pain), PASCAL (ditto but worse, pointers are so confusing), Modula-2 (the bas...illegitimate child of PASCAL - avoid like the plague!), C++ (2 weeks is not long enough to learn it - hell, two years wouldn't be enough!), PROLOG (5, I think - hated it), Visual BASIC 5 (I quite liked it, inventing a technique - or so I thought - that turned out to be SOP), VB.NET and DCL (v. powerful if you know what you're doing). Also 6502, 80386 (not bad, actually - HiSoft Assembler was very capable), Z80 and 68000 Assembler (loved the last two).
Cautionary note: on my HND/degree course I used the VT220 and VT320 keyboards. The < and > symbols were on the same key, needing SHIFT for the latter. I missed this once. One typo, just ONE, i.e. a misplaced < that should've been >, and it cost me EIGHT BLOODY HOURS of debugging a COBOL program! Just to make it even more baffling, a fellow student had virtually the same program, with the same design (JSP tends to force this, especially in COBOL - one advantage of COBOL with JSP is that it's difficult to misinterpret) - but his program worked perfectly with his and my data file!
I swear, I was just about to lose the will to live when, after EIGHT BLOODY HOURS, I finally spotted it. An excellent example (so my lecturer teased me later) of a logical error as opposed to a compiler error - the compiler, of course, never caught it as it was a perfectly legitimate program statement; it only counted as a typo because it was the wrong symbol, not an illegitimate one. Never was GIGO so true!

Oh, I miss the VIC-20/SHARP MZ700/ATARI ST, 6502/Z80/68000 days. Back then IT made sense.
