Definitely my laptop -- it's usually sitting on a TV tray in the family room and I get to use it while my son is playing or watching TV, or my husband is doing something
I wouldn't get anywhere near as much opportunity to digiscrap if I had to do it at our desktop in our home office.
Currently i'm on a desktop, but i hope to be on a laptop very soon. Maybe i'll get one for my birthday or christmas! I think i would love the mobility of the laptop! I think i as well would take it with me everywhere!!!!
