Dell makes a solid product.  This particular version has a pointer stick... a small button in the center of the keyboard which offers an alternate way to move your cursor.  After watching my cursor move on its own, I contacted Tekrefurbs.com who immediately sent a prepaid return label for an exchange.  While at it, I asked for additional RAM and a larger hard drive.  Impressive how quickly they responded to my needs.  Customer service was very friendly and cooperative.  Very rare!  Reminded me of the old days! (lol)  I will shop techrefurbs.com from now on for my computer needs.
