I just signed up for the online course to get certified, which will be followed by the hands on course, and a laptop with wifi is required for the class. I don't currently have a laptop, and I know I'll need one for the field, so I'm curious what some of you use. I know it's mainly to get inside the modem, and a guy I shadowed for a day was using something like this http://www.jr.com/asus/pe/ASU_1025CMU17BK/ small, lightweight, and good battery life. This would be fine for my hands on training as well, I'm assuming, but I figured it wouldn't hurt to ask the people that do it every day, and get some feedback. Thanks in advance!
