I'm a real lightweight ... I do online research, email, keep an online calendar, run our bookkeeping system, store photos ... all stuff that requires little from today's computer.  Della is the perfect size, light enough for travel, speedy and even has a lighted keyboard.  It was scary to buy something 'refurbished' but a year ago laptops were expensive, so I took the chance.  Very, very happy.  I just bought another one to replace my office laptop.  She does very well with a wireless keyboard and mouse plus an external monitor.  How did we manage life without Amazon???
