I am a grandmother who uses Lenovo Think Pads but know very little about computer technology. This machine is about three years old and has Windows 7 and the new one has the same Windows 7? Has there been more recent windows. The second thing is that I asked about things like the processor but he said that this was fine. I ordered the machine in line as I use the red tracking ball and am used to IBM or Lenovo so just ordered a machine. Now I realize that I do not know what the processor speed is or what the windows is etc. Is the new computer up to date for what is out there. It was 800 something dollars. I thought that would be ok for me. It had been higher priced.
