Ken Layton:
Every single compact fluorescent light I've bought has had slow warm up problems.

patrickl:
Bought 10 years ago or recently?

The globes I got for the bathroom vanity are the worst in terms of warm up and they are the newest CFLs I have.  I think I got them at Sam's Club sometime this year, but I can' remember the brand.  I like the energy savings, but I ended up taking them out of the guest bathroom because of the annoyance.  I also have some spot light type CFLs for the cans in the basement, which also are terrible in terms of warm up duration.  The normal 13 watt CFLs are way better, but they do also get brighter after a warm up.  Why do these require such a warm up period in the first place?  My normal tube fluorescent lights (even in the cold garage) do not seem to require any warm up period.

ChadTower:

I don't have a single CFL in my house that takes more than a couple of seconds to warm up and stabilize.  That is probably 20-25 CFLs of various ratings in fixtures that start at 20 years old and many are far older than that.

ahofle:
Do you have of the enclosed type CFLs like the globes and floodlights?  I wonder if there is something with those (lack of ventilation possibly as mentioned above) that makes them so much worse at starting up than the normal CFLs?
