Heading back to school for an MBA and need a something to get through. I have not purchased a laptop for almost 15 years and I know technically is now a whole new world. The main use will be school. I’d say 99% Microsoft office applications & Zoom classes until the plague is over. No need for CAD, FEA or any programming applications so just a simple unit. Some preferred options: 8+gb ram Sub 15” size 500gb+ storage I5 processor 8th gen or newer Preferably under $600 Windows Operating system Open to used options as well. Any Tech guru’s have any recommendations?
