Screw all that. You're probably doing the basic computing that a retired senior does - web browsing and Office. Go to Costco, Sams, or Best Buy and get whatever big screen laptop they have on sale. The technology has progressed so much you won't be able to tell the difference among them. If you spend more than a $1k you've been taken. Also I've bought so many refurbed units over the years and none of them have outright failed me. We have 2 now, a laptop and a desktop. My wife likes a desktop so I got a refurbed HP that's the size of a large paperback. Hook up a keyboard, mouse and monitor and she's a happy camper. The thing to consider is if you want to make the change to an iPad instead of a laptop. They offer the ease of portability and if you want the feel of a traditional laptop you can get bluetooth keyboard and the works.
