The one I have on XP is a desktop. It's a reasonably current Fujitsu Siemens that I found in our back lane after some students left the area. I took it home, basically for spare parts, but when I plugged it in it worked. Reformatted the drive, added two more 80GB hardrives and now it is ready to put some of my photos onto it. 280 GB of storage space for free.
