Right, ours do the same (don't dim even if you turn them down). The difference, though is that we get a noticeable hum from the dimmer switch if all the bulbs are CF, even if it's turn up to full brightness. If I put one incadescent in the mix, the hum goes away and the dimmer controls the incadescent while the CF's stay bright. We never really use the dimmer, so it's no big loss. And like you, we seldom use the dimmable cans at all, but have a table lamp on each side of the bid and a floor lamp by a chair. Eventually, I'll order some dimmable CF's (and I know they'll cost a lot more), but it's just not a priority.
