That's true, but it leaves out the other half of the equation: you'll still likely spend less of your valuable time on your making your Ubuntu installation work, than on anything else (speaking as someone with commercial dev experience on MacOS, Windows, Linux, and FreeBSD).

I spent hours trying to stabilise my wife's XPS13 after a recent Windows Update sent it into paroxysms of BSODs. Reset, reimaged, the whole nine yards: nothing. Ended up installing Ubuntu on it and it's been rock-solid stable since.
