I have found the product very efficient and it lived up to the expectations that I had arising from my reading of the Which? review of this computer and the recommendations from a member of my family. I have awarded the product five stars because I found it easy to set up and use. Its portability is very good (I used it to replace a dying desk top computer) and I find I can take it and use it for historical lectures (Powerpoint presentations) with ease. I look forward to a long and happy partnershup!
