I'm adding now data from Apr 3 → May 1, 28 days. Nothing really new in
April, the same tendencies got a big stronger.

In April, compared with January:

- Windows users went from 72% to 73% (+1.8%)
- macOS users went from 4% to 7% (+3.5%)

In April, compared with January:

- "back" from macOS went from 5% to 15% (+9.9%)

In April, compared to January:

- Windows    -1.2%, I don't know how to explain this number...
- macOS        +6.8%
- Linux        -1.2%

Now 75% of USB images and downloads have lowered a bit since March (-8%)
