That was my first response to Linux when I was first trying it out. Back in the mid 1990s.
At the userland level especially, it didn't suck, and (with the GNU userland, windowmanagers, etc.), in fact, sucked radically less than stock commercial Unices I'd been using at the time (Sun, HP, AT&T, Data General, BSD).
The situation's only gotten much, much better.
I'll occasionally find myself in situations where I'm connecting to commercial Unix boxes (was a semi-recent shop where a fair number of staff still ran CDE desktops), and, really, it's painful. Doable, but painful.
