When I was thinking about buying this.It was to hook up a Windows Me for my 7 yr. old Autistic nephew.He enjoys the screensavers so much!!Another family member was over and brought a new laptop.We hooked up everything and found that the only way this will work is only one at a time can be used.It totally zapped all the speed of my home computer.So if you buy this be forewarned.One at a time.
