I travel every day with my laptop situated on passenger seat desk. I used it for my schedule and CRM. Then lots of word processing and excel spreadsheet. Very light video editing. Then hotel stays 2-4 nights a week and my sole source of entertainment. My laptop died now I need to buy a new laptop. I was originally going the new M2 13 but with the 15 was wondering if I should limp along with my tablet for a month. With refurbs the 13 is much cheaper in my expectations. Is the size the only difference?
