I don't work in the computer field but I have a better than passing knowledge of how to use computers, and I'm resigned to buying a new PC based laptop every three years or so because they just start to slow down and one needs the upto date technology, etc etc. I need a new laptop now (my vaio has reached the end of its efficient life and ive decided on a Lenovo after thorough research) I've been waiting for the new Windows 10 to come out so I can buy the new machine with that installed. but what are these guys at Microsoft upto????....can't they give us a set date and deliver on that??? high time they got their act together.......otherwise another customer will just move on to APPLE!!!
