This is a FYI for people thinking about buying an Acer desktop with the hopes of a free Windows 7 upgrade.   On July 3, 2009 I went into a local Best Buy looking at desktops. I saw the Acer x1700 and asked 2 different sales people if it was eligible for the free Windows 7 upgrade. TWO sales people, both of whom told me that it was certainly eligible. So, believing them, I brought it home, set it up and tried to register for the free upgrade. I got a message saying that my model was NOT eligible. I went back to BB and had TWO MORE people tell me that it should be eligible. One of them was a Geek Squad tech who tried really hard to find out what was going on, even got me a number to call to reach a human at Acer.   Upon reaching a human at Acer, I was initially told that it was eligible, only to have the tech then put me on hold and come back to tell me that it ISN’T.    Because of this run-around and lack of usefull information, I brought the computer and all its components back to BB and I will not be buying another computer from BB or Acer. HP/Compaq and Asus both have a list of their eligible computers availible for review on their web sites, unlike Acer, unlike Best Buy, who is selling these computers to consumers.  I truely feel Acer and Best Buy are misleading the public when they promote and sell computers that they insist are eligible for a free upgrade when they are not.   I have seen posts saying that BB is working out a similar issue that they are having with another computer company. I hope that they are going to be working this out with Acer as well, for the other people who are dealing with this craziness. I also hope that they are educating their sales people, who are still pushing these ineligible computers onto people.
