For real. Maybe it is just me, but I find programs like Photoshop and nearly every CAD program I've ever encountered to be bewilderingly complicated. I don't use any of those sorts of software professionally, but have found myself needing them numerous times for hobby reasons. Every time I try to learn them I become frustrated with just how steep and tall the learning curves are.

Git though? I felt pretty confident with how it worked and basic command line operation after just a weekend.

Maybe git's command line is more inconsistent than hg's or subversions', but in the grand scheme of software difficulty? I just don't get the complaints. "Incomprehensible"? Give me a break. It does not hold a candle to most commercial professional software.
