Two new results are included in this presentation. First, we arrive at a simple (but accurate) phenomenological expression for the semiclassical distribution function of electrons in the presence of electron-electron scattering. Second, it is shown that in thin samples, low-frequency shot noise may be large even if the sample length is much larger than the electron-phonon relaxation length.7 pages, 2 figures, to appear in "XVIII Rencontres de Moriond: Quantum Physics at Mesoscopic Scale", Edited by D.
