Some of my first brews had a lot of sediment that didn't drop before I bottled, and it was a real problem that needed to be left behind when I poured. My best bottles yesterday had just a thin layer, and only about an ounce of beer left behind in a liter bottle was probably still more than I needed.
If I had poured it, it would have clouded and foamed the glass, and left a little grit... but I've seen that in some commercial beers, too. I don't really mind it as much, but it can cause some intestinal distress if you're not already used to unfiltered beer and yeast.
Save yourself the extra grit and beerfarts- use a glass.
