I start with a review of warm inflation and how it differs from the
standard inflation paradigm.  I then discuss the results of recent,
detailed, quantum field theory calculations that show many generic
inflation models, including hybrid inflation, which were believed only
to have standard inflation regimes, in fact also have regimes of warm
inflation.  These results dispel many foregone assumptions generally
made up to now about inflation models and bring to the fore various
elementary issues that must be addressed to do reliable calculations
from inflation models.  I then dicuss the analysis of warm inflation
in several well known SUSY models including MSSM and NMSSM.  Density
perturbations and observational consequences of warm inflation in
these models, especially related to WMAP, are also discussed.
