I'm guessing that I.R. have an inside line on a future
government regulation that all CFLs will have to have a
power factor higher than 0.9 that will make all the simple
designs obsolete.

Your and MooseFET's idea of "simple" may not quite fit with us pros'
definition where "working" means "properly, as specified, for a period
longer than the warranty".

And parts count and simplicity do not correlate.
