Personally, I think it is ok to buy air. According to your description, writing papers and occasionally retouching pictures should be enough. Can be used for a long time. If the money is really not bad, then there is nothing to worry about. If you buy expensive ones, you have the advantage of being expensive. The hard disk is bigger and the memory is bigger. In fact, I think you can buy your own memory and hard disk, and you don't need 6000.
