Summary
Blazars are clearly variable in all spectral bands, and
their variability places additional constraints on their structure
and emission processes. This presentation covers the current results
and future opportunities regarding variability of blazars as measured
in the X-ray band. In particular, it highlights recent results from
observations with the Asca, RXTE, XMM, and Suzaku satellites, and discusses
the potential for studies of X-ray variability (including observational
constraints, and anticipated results) from broad-band studies in the GLAST era.
It also discusses the future missions - such as NuSTAR, NeXT, and Con-X -
that are likely to provide new insight on blazar structure, especially via the new
data resulting from sensitive time-resolved observations in the hard X-ray band.
