Worked in computer field since 1963. Worked for major manufacturer for 20+ years. Then started my own company, we did anything needed for small businesses. Sold it 12 years ago and retired. I use nothing but a laptop / notebook anymore. They generally have the capability of a desktop or more. They are compact and very rugged.
I would recommend purchasing a major brand. My favorites are HP or Dell. The reason is if you should need maintenance, they can and will be abe to provide needed service and support! This is very important with a laptop.
