In order to get the partitioning the way I wanted it (2 ntfs partitions) I had to buy another copy of xp. The acer discs are useless as they will restore it to the manufacturer defaults only.
I went to acers website and downloaded all of the drivers. There are some extras, so I think that the lower priced model uses a different wireless and modem.
Don't know, but don't have any reason to believe that the lower price won't have the same drive.
