The Toshiba Satellite L850 is a great system. Plenty of power, full size keyboard and large touchpad for the mouse. Come complete with all the main things you need out of a laptop (wifi, generous size hard drive, i5 processor with plenty of power, 4GB of ram, bluetooth)
Speaker is fair quality. This laptop has 3 USB ports (2x 3.0 USB and 1x 2.0 USB) plus HDMI, ethernet port and a port for an external monitor/projector. The included battery is a 6-cell.
