Query: Is power-law inflation really attractive?   It is argued that the order of the analytic expressions for the calculation
of the primordial perturbations from inflation exerts a strong influence upon
the results of the analysis of observables dynamics based on these expressions
and, therefore, upon some predictions sometimes taken for granted as generic
for the inflationary scenario.
