6. They look ugly. Some light fittings are designed for particular
bulbs - we have candles in some, just for aesthetics and s** the lifetime.

In certain cases they simply won't physically fit. Even those lamps which
have a similar shape to incandescents are often longer/larger.

At the moment, CFL's larger than 11W (40W real equivalent) will
always be larger than their filament equivalents. Technology is
slowly allowing CFL's to be made smaller, and that cross-over
point is slowly increasing. Note however that generally, the
smaller the CFL, the less efficient due to increase in the
self-shadowing of the tube. Most efficient ones tend to be
spirals with the spiral as open/stretched as possible (and no
outer bulb, except where used in exposed cold/draftly locations).
